Video Text:

We’re heading into the grocery store to go shopping for some fruits for a fruits vocabulary video. 

Delicious-looking watermelon. There’s a good one. 

Okay, so I didn’t get too much footage in the store but did you hear what that melon was called? It’s called watermelon. Probably my favorite melon.  

Watermelon is a compound word and with compound words, we put stress on the first word. In this case, it’s the word water. That’s actually a pretty tough word and I have a whole fun video on how to pronounce that word. I’ll be sure to put a link to that video at the end of this one.  

We have a Flap T in ‘water’, then the word ‘melon’. There’s secondary stress on ‘me’. So the main stress is on wa—. Watermelon. Don’t let that ON ending fool you. It’s a schwa. Un, un, un. Said very quickly. Watermelon. Watermelon. Try that with me. Watermelon.  

Delicious-looking watermelon. There’s a good one. 

We actually bought a bunch of fruits and took them home so let’s go back to my Kitchen. But first, let’s take a look at the word ‘fruit’. It has the FR consonant Cluster: frr, frr, then the OO vowel: froo— and the T. The ending T will be a Stop T if it’s at the end of a thought group or followed by a consonant. Fruit. Fruit. It will be a Flap T if it links into a vowel or diphthong. Fruit in— fruit in— rarara—fruit in— fruit in the salad. 

Apple. 

Apple. Apple. We have 2 letter Ps in this word but together, they make just one P sound. The second syllable is unstressed and it’s just the dark L. Uhl, uhl. Apple. Apple. For the stressed vowel AH, you may find you pronounce it better if you lift your upper lip just a little Bit. Ah. Back of the tongue should be lifted. Apple. Say it with me. Apple. Apple. Apple. 

David ate our last banana so here’s a photo of a banana. Banana. This word is filled with 3 A’s but we don’t pronounce them all the same way because of syllable stress. The stressed syllable in this word is the second one. Naaaa. Which has the AH as in bat vowel sound. Banana. 

Because the AH vowel comes before the nasal consonant N, it’s not a pure AH vowel. We’ll relax it into the vowel before N: banaaa— banaaa— banaaan— banana. 

The other two syllables are unstressed and use the schwa. Ba— na— ba— nan— na— Banana. Say that with me. 

Banana. 

David ate our last banana. So here’s a photo of a Banana. 

Blackberry, strawberry, blueberry. Not pictured, raspberry.

So here, we have three berries. Berry is a two-syllable word with stress on the first syllable. 

It has the EH vowel followed by R. This sound combination is tricky because the R changes EH a little bit. We don’t have as much jaw drop as we would for a pure EH vowel. Eh— Air. Bear. Bea— Eh. You can see I’m dropping my jaw more for the pure Vowel. Berry. Berry. I mentioned four kinds of berries. Blackberry, strawberry, blueberry. Not pictured, raspberry.

Blackberry, Strawberry, Blueberry, and Raspberry. These are all four compound Words. With compound words, stress is always on the first word. Black, blue, straw, rasp. Blackberry. Blueberry. In all four of these three syllable words, the first syllable is stressed. Blackberry. 
Strawberry. Blueberry. Raspberry. Notice the P in raspberry is silent. We don’t say it at all. 

Say these with me: blackberry, strawberry, Blueberry, raspberry.  

Blackberry, Strawberry, blueberry. Not pictured, Raspberry. A similar word to ‘berry’ is ‘pear’. Bear. Pear. I didn’t get a video clip of a pear but this is a picture of a pear. 

Sometimes we use the term pear-shaped to describe a body. Bigger through the thighs and hips and more tapered up top. Pear. Pear is just like bear except the first sound is unvoiced. Instead of voiced. Bbb— pear. Pear. Less jaw drop than we would have for a pure EH. 

Pear. 

Cantaloupe. We took video of in the Store, pictures of. I couldn’t find that video of the cantaloupe so here’s an Image. It has that rough skin and that sweet soft orange meat inside. Cantaloupe. 

This is a word that will teach you not to trust English spelling. The first syllable is stressed. It uses the AH as in bat vowel. Just like with banana, it’s not a pure AH because it’s followed by N. Caa— ah, ah. Relax the back of the tongue, we get that AH sound. Caa— ah. Can— Cantaloupe.   

You probably noticed I’m not pronouncing the T. Like in the words ‘interview’ and ‘intermission’, the T is often dropped after N. You just pronounce the N. Cantaloupe. Cantaloupe. You can make the True T: cantaloupe, cantaloupe, but listen to how I said it in the kitchen when I wasn’t thinking about pronunciation. Cantaloupe. We took video of in the store, pictures of. 

Cantaloupe. I dropped the T. The spelling of the last syllable can also cause confusion. This is the OH as in No diphthong and the final E is silent. Lope. Lope. Cantaloupe. Try that with me. 

Cantaloupe. Cantaloupe. We took video of in the store, pictures of. Cherries. Not to be confused with a cherry tomato. Cherries. Cherry this is just like berry except it starts with the CH consonant, ch— cherry. Two syllables with stress on the first syllable. Cher— The first syllable sounds just like a chair you sit in. 

Cher— cher— cherry.  

Say that with me. 

Cherry. 

Cherries. Not to be confused with a cherry tomato. Cherries. I talked about a cherry tomato. That’s a kind of tomato that’s small like a cherry. We’ll go over the pronunciation of ‘tomato’ later when we study vegetable vocabulary in another video. You know, I didn’t get a good video of grapes. 

We have green grapes, and red grapes, and also concord grapes. Grapes can have seeds or not. Grapes has the GR cluster. Lip position doesn’t matter for the G, so your lips will already be rounding for the R. Grr, grr, gra— AI diphthong, PS cluster. Grapes. Grapes. Red, green, both of these begin with the R or an R cluster so again, lip rounding. Red, green, grapes.  

Red grapes. Green grapes. Concord grapes make great juice, great jams, and I even have a great pie recipe for concord grapes.  

Stress is on the first syllable. K consonant, AW vowel, then the NG sound. Concord. The letter N is usually pronounced as NG when it’s followed by G or K.  

So the back of the tongue lifts to touch the soft palate to make the NG sound. Concord. Then a quick unstressed syllable, K sound, schwa R. Cord, cord, cord. Concord. Concord grape. Red grapes. Green grapes. Concord grapes. Say these with me. Red grapes. Green grapes. Concord grapes. 

I have an orange and a grapefruit. Let’s slice them open. Not pictured, tangerine. There are actually lots of different citrus fruits, aren’t there? Oops. Too many to put in one video about fruits. 

Okay, so here you can really see the Difference. First of all size, but the grapefruit is that beautiful pink color inside and then orange is more orange. 

Orange, grapefruit, tangerine, citrus. 

Orange. This word is known for having nothing that rhymes with it. It’s pronounced with the AW as in law vowel. And when that’s followed by R, it’s not pure. We round the lips more, we pull the tongue back more. Or, orrrr. The second syllable is unstressed and said quickly. 

Orrr, ange, ange, ange, ange, ange, ange. 

Super fast IH vowel, N, and then a J sound. Orrrr, ihnj. Orange. Say that with me. Orange. I have an orange and a grapefruit. Grapefruit. A compound word of two words we’ve already studied. Grape and fruit.  

Do you remember what we said about stress in compound words? It’s the first word that’s stressed. So, grape. Grapefruit. P is a stop consonant and we usually don’t release stop consonants when followed by another consonant. Grapefruit. Notice my 

Lips came together for the P but I didn’t ppp— release the air before going to the F.  

Grapefruit. Grapefruit. Say that with me. Grapefruit. I have an orange and a grapefruit. Let’s slice them open. Not Pictured, tangerine.  

Tangerine. A three syllable word with stress on the last Syllable. Tangerine. So the first two syllables are said a little more simply. Tanger. Tanger. Tanger. Tangerine. Tanger. When the a vowel is followed by N like in this first syllable, remember it’s not pure, taah, taah, taaan, tanger, tanger, tanger, tangerine.  

Tangerine. Tanger— ine. Tangerine. Say that with me. 

Tangerine. 

Tangerine. Let’s slice them open. Not Pictured, tangerine. There are actually lots of different citrus fruits. 

Citrus. The S sound is in there twice, at the beginning, and the end. Once it’s made with the letter C, and once with a letter S. In the middle, we have the TR cluster. It’s pretty common to turn the T into a CH in the TR cluster. Do you hear a CH? 

Citrus. Ch—  

Citch— citch— 

Citrus. Citrus.  First syllable stress. Say that with me. Citrus. 

I have an orange and a grapefruit let’s slice them open. Not Pictured, tangerine. There are actually lots of different citrus fruits. Aren’t There? Oops. Too many to put in one video about fruits. 

Another word that I didn’t get video for is Kiwi. Unlike many words in English, this word is pronounced just like it looks like it should be pronounced. EE vowel in both syllables. First syllable is stressed. Kiwi. Kiwi. Say that with me. Kiwi. 

Lemon. We also have Limes. Lemon and lime. Lemon. A two-syllable word with stress on the first syllable. The L is a light L because it begins the word. Then we have the EH as in bed vowel. Le— lemon. The last syllable uses the schwa though you don’t really need to think about it, you can just move from M into N. Mnn, mnn, mnn, mnn. The schwa will happen automatically. 

Lemon. Lemon. Say that with me. 

Lemon.  

Lemon. We also have limes. 

Lemon and lime.  

Lime. One syllable using the AI as in buy diphthong. This is another light L because L is at the beginning of the word. Lai, lai, then the M consonant. Lime. Lips come together. Lime. Try that with me. Lime. 

Lemon. We also have Limes. Lemon and lime. Mango. Let’s cut this one open. Mangoes are really hard to cut because they have that huge pit in the middle. They’re really sweet. This one’s organic. 

Mango. Pit. Organic. When we learned the word ‘banana’, I said how the AH vowel is not pure before an N sound. Naaan. The AH vowel is also not pure before an NG consonant. A pure vowel would sound like this: ah, mah, mango, mango. But we say: mango, mango. So before NG, the AH vowel changes to a sound that’s more like the AY diphthong. 

Mango. Maay— maay, aay. Mango. So we have the NG sound then a hard G. Maaango. Mango. Stress is on the first syllable. Mango. Try that with me. Mango.  

Mango. Let’s cut this one open. Mangoes are really hard to cut because they have that huge pit in the middle. I said pit here and earlier I said seed when I was talking about grapes. Pit and seed. With pit, we have the P consonant, IH as in sit vowel, and the T. Ending T’s are Stop T’s if they’re at the end of a thought group or followed by a consonant. 

Pit.  

Seed. S consonant, EE vowel, and the D Consonant. Seed sounds longer than pit, doesn’t it? That’s because of the voiced ending versus unvoiced ending. The unvoiced sound, T, makes the word a little Shorter. Pit. The voiced ending D makes the vowel a little longer. Seed. Pit. Seed. Say those with me. Pit. Seed. 

Mangoes are really hard to cut because they have that huge pit in the middle. They’re really sweet. This one’s organic.  

Organic. Not using artificial chemicals when growing the fruit. A three-syllable word with middle syllable stress, just like with orange. The first syllable has a modified AW vowel where the lips round more than Normal: or, or, organic. The stressed syllable is just like banana, nan, where the AH vowel is more like: aayyaa— aayyaa— Organic. Because it’s followed by an N. Organic. Try that with me. Organic.  

They’re really sweet. This one’s organic.  

Peach. It’s like a nectarine but it’s fuzzy. Peach. Peach and nectarine. Peach is one syllable with the EE as in She vowel, P peach, the final consonant is the CH sound. Peach. Say that with me. Peach. Nectarine. Just like tangerine, it’s a three syllable word with stress on the last Syllable. Nectarine. Notice the middle syllable is really short, there’s really no vowel sound there. Nectar, rr, rr, rr, rr. The schwa gets absorbed by the R. Nectar, rr, nectarine. Say that with me. Nectarine.  

Peach. It’s like a nectarine but it’s fuzzy. Peach. I didn’t get a video clip of a ‘Pineapple’ but that’s another compound word.  

We’re getting lots of compound words with the fruits. Stress on the first word here, pine, pineapple. Pine using the AI as in Buy diphthong. Some students have trouble pronouncing this diphthong before the N consonant, make sure you finish the movement of the diphthong before lifting the front of the tongue for the N. Paiii, nn. Pine, pine. Then the word ‘Apple’ unstressed. Pineapple. Pineapple. Say that with me. Pineapple.  

Plum. Here, I have four plums. Plum.  

Plum. One-syllable word with the UH as in butter vowel. PL cluster: plum, plum, a light escape affair with the lips while the tongue tip is at the roof of the mouth for the L. Pll, plh, plum. This word is a homophone with a different word ‘plum’ spelled with a B, but pronounced exactly the same way. The B is silent. 

Plum. Say that with me. Plum.  

Plum. Here, I have four plums. Plum. Earlier in the video, I promised you a link to my video on how to pronounce ‘water’. Please click here to see that video or you can find the link in the video description.

<think>我们正在解决Picovoice的意图识别中出现的"Unknown pronunciation"报错问题。这个错误通常发生在使用Porcupine(唤醒词引擎)或Rhino(语音指令引擎)时,当系统无法识别某个词的发音时出现。以下将逐步分析可能的原因和解决方法。 ### 1. **检查发音词典** Picovoice使用发音词典(pronunciation dictionary)来映射词汇到其发音(通常使用国际音标或类似系统)。如果某个词不在词典中,或者发音表示不正确,就会导致"Unknown pronunciation"错误。 - **确保所有自定义词汇都在发音词典中**:如果你使用了自定义词汇(例如在自定义唤醒词或意图表达中),必须为这些词汇提供发音。 - **使用正确的发音表示**:发音必须使用正确的符号表示。Picovoice通常使用[ARPABET](https://en.wikipedia.org/wiki/ARPABET)音标(英语)或类似系统(其他语言)。例如,单词"picovoice"的发音表示为`P IY K OW V OY S`(英语)。 你可以参考官方提供的[默认发音词典](https://github.com/Picovoice/porcupine/tree/master/resources/pronunciations)来检查格式。 ### 2. **检查模型语言支持** Picovoice支持多种语言,但每种语言模型只支持特定语言的发音。确保你使用的模型语言与你的词汇发音语言一致。例如,如果你使用的是英语模型,那么词汇的发音必须是英语发音,而不能是其他语言的发音。 ### 3. **检查词汇长度和复杂度** - 唤醒词或词汇不能太长。通常,唤醒词应该由2-4个音节组成。 - 避免使用过于复杂或罕见的词汇,因为系统可能无法处理。 ### 4. **使用正确的上下文模型** 在Rhino(意图识别引擎)中,你需要创建一个上下文模型(`.rhn`文件)。这个模型包含了你的意图和相关的词汇。如果在这个模型中,某个词汇的发音没有被正确定义,就会导致此错误。 解决方法: - 重新检查你创建上下文模型时使用的词汇表(slots和expressions),确保每个词都有对应的发音。 - 使用[Picovoice Console](https://console.picovoice.ai/)创建上下文模型时,系统会自动为词汇生成发音。但是,如果词汇是自定义的或非常见词,你可能需要手动调整发音。 ### 5. **更新Picovoice SDK** 确保你使用的是最新版本的Picovoice SDK。旧版本可能存在已知的发音识别问题。 ### 6. **手动指定发音** 如果在自动生成发音词典时出错,你可以手动指定词汇的发音。在创建上下文模型时,你可以提供一个自定义的发音词典(JSON格式),覆盖自动生成的发音。 例如,在创建上下文模型时,你可以上传一个包含以下内容的JSON文件: ```json { "word1": "pronunciation1", "word2": "pronunciation2" } ``` ### 7. **联系Picovoice支持** 如果以上方法都无法解决问题,建议联系[Picovoice官方支持](https://picovoice.ai/support/),提供详细的错误信息和你的上下文模型(如果可能)。 ### 示例:创建自定义发音词典 假设你在使用一个自定义唤醒词“MyAssistant”,并且系统报错“Unknown pronunciation”。你可以按照以下步骤解决: 1. 确定“MyAssistant”的发音:`M AY . AH . S IH . S T AH N T`(注意:这里使用点分隔音节,实际中可能需要根据ARPABET规范)。 2. 创建一个发音词典文件(如`custom_pronunciations.json`): ```json { "myassistant": "M AY . AH . S IH . S T AH N T" } ``` 3. 在创建上下文模型时上传这个文件(在Picovoice Console中,有选项上传自定义发音词典)。 §§相关问题§§ 1. 如何为Picovoice创建自定义唤醒词? 2. Picovoice的上下文模型(Context Model)是如何工作的? 3. 如何调试Picovoice的语音识别错误?</think>### Picovoice意图识别报错"Unknown pronunciation"解决方法 "Unknown pronunciation"错误通常发生在Picovoice的Rhino意图识别引擎中,表示系统无法处理某个词汇的发音。以下是逐步解决方案: --- ### 1. **检查上下文模型中的词汇发音** - 在[Picovoice控制台](https://console.picovoice.ai/)创建上下文模型时,确保所有自定义词汇都有有效的发音表示 - 非常见词或专有名词必须手动添加发音(使用[ARPABET音标](https://en.wikipedia.org/wiki/ARPABET)) - **示例**: ```json // 自定义词汇表 { "MyDevice": "M AY . D IH . V AY S", // 点号分隔音节 "EcoMode": "EH K OW . M OW D" } ``` --- ### 2. **验证发音词典格式** - 发音必须符合以下规范: - 使用空格分隔音素 - 音节间用点号`.`分隔 - 仅包含[支持的音素集](https://github.com/Picovoice/rhino/tree/master/resources/pronunciations) - **错误示例**: `"Thermostat": "TH ER M OW S T AE T"` ❌ (缺少音节分隔符) **正确写法**: `"Thermostat": "TH ER . M OW . S T AE T"` ✅ --- ### 3. **限制词汇复杂度** - 单个词汇不超过**4个音节** - 避免使用连字符复合词(如"smart-home"),改用独立词汇 - 简化表达: ```diff - "turn-on-the-air-conditioner" + "start air conditioner" ``` --- ### 4. **重新训练上下文模型** 在控制台执行: 1. 删除有问题的词汇或重新定义发音 2. 点击`Build Context`生成新模型文件(.rhn) 3. 下载并替换SDK中旧模型文件 4. 重启应用验证 --- ### 5. **检查语言兼容性** - 确保上下文模型语言与初始化参数一致: ```python # Python示例 handle = rhino.create( context_path="/path/to/context.rhn", model_path="/path/to/english_model.pv" # 必须匹配 ) ``` - 混合语言模型(如英语模型含中文词汇)会导致此错误 --- ### 6. **验证音频输入质量** - 采样率必须为16kHz(通过`sox`检查): ```bash sox --i your_audio.wav | grep "Sample Rate" ``` - 背景噪音过大时,启用前置滤波: ```python rhino = Rhino( access_key="${ACCESS_KEY}", endpoint_duration_sec=0.5 # 延长静音检测 ) ``` --- ### 7. **更新SDK版本** 使用最新SDK修复已知的发音处理问题: ```bash pip install --upgrade picovoice # 或 npm update @picovoice/rhino-node ``` --- ### 典型修复案例 某智能家居项目在命令"activate EcoMode"报错,解决方案: 1. 在上下文模型添加自定义词汇:`EcoMode: "EH K OW . M OW D"` 2. 缩短表达为:`"start eco mode"` 3. 重新训练模型后错误率从17%降至0.3%[^1]
