Coqui Cantonese Development Notes

粤语TTS实现笔记

1. Implement Cantonese Frontend

参照文档Implementing a New Language Frontend 和 普通话代码实现相应的粤语部分

在https://github.com/coqui-ai/TTS/tree/dev/TTS/tts/utils/text/phonemizers实现粤语的phonemizers。

关于phoneme，不知道coqui的普通话部分用的是什么标准，有点像IPA，但又不是。例如"ao": ["aʌ"],在IPA里没有ʌ。也许可以参考amazon的文档实现粤语的phoneme映射：Chinese (Cantonese) (yue-CN)（可能在wikiepedia里Jyutping 是一样的系统），再查一下eSpeak里面用的是不是一样的。尽量往IPA和eSpeak方向统一（如果发现eSpeak总体和IPA一致，但有些不同，可能需要修正eSpeak）。

2024-9-4

Implemented cantonese/jyutpingToPhonemes.py. Use pycantonse.jyutping_to_ipa (https://github.com/jacksonllee/pycantonese/issues/44) to do the translation. pycantonese is a useful Cantonese Linguistics and NLP library. The result of pycantonse.jyutping_to_ipa should be same to wikipedia. The IPA map in amazon seems not fully the same to IPA in wikipedia. It seems that situation in eSpeak is more complicated and I don't want to touch it. I plan to modify other phonemizer files tomorrow.

2024-9-5

Finish cantonese phonemizer. code at https://github.com/hgneng/TTS

reinstall conda coqui environment.

pycantonese's copus is not complete enough. "这是，样本中文。" is translated as ||si6||||||bun2||zung1|man2||| Two characters are missing. I need to write my cantonese to jyutping python module myself (or extend pycantonese).

2024-9-6

使用opencc模块把文本统一转换为繁体中文就可以使用pycantonese了，无需扩展pycantonese。

下面的步骤不太确定，没有找到config.phoneme_language，不知道实现是否正确。

https://docs.coqui.ai/en/latest/implementing_a_new_language_frontend.html

After you implement your phonemizer, you need to add it to the TTS/tts/utils/text/phonemizers/__init__.py to be able to map the language code in the model config - config.phoneme_language - to the phonemizer class and initiate the phonemizer automatically.

下面这个步骤暂时没有做（TODO1）：

You should also add tests to tests/text_tests if you want to make a PR.

这个项目有粤语语音库（8G，仅用于学术研究），音质很好，属于播音员级别的录音。

https://github.com/HLTCHKUST/cantonese-asr

P.S. Orca在Firefox上有很多快捷键，输入中文时会触发这些快捷键，这导致输入中文很困难。

2. Training Model

参考文档：Training a Model ，先和普通话一样，选择Tacotron2模型，以后考虑使用xtts模型。

似乎参考这个例子，调通了就能训练：https://github.com/coqui-ai/TTS/blob/dev/recipes/kokoro/tacotron2-DDC/run.sh

2024-9-9

MDCC Dataset requires a signed license, I send it today.

I plan to read its paper later: http://arxiv.org/pdf/2201.02419

The paper said  "Common Voice zh-HK"(from wikipedia in 2019) is "the biggest existing dataset". I should take a look at it some time later.

2024-9-10

Read 3/8 of the paper.

copy kokoro foler to mdcc and modify based on it: recipes/mdcc/tacotron2-DDC

Don't understand setting in characters in tracotron2-DDC.json. It seems not correct but it may has no use.

Ready to train tomorrow.

2024-9-11

Finish paper reading. MDCC use "Fairseq S2T Transformer" to do the training. Use CER(character error rate) as evaluation metric and result of 10.15% comparing to 8.69% with Common Voice zh-HK. (What's the advantage of MDCC??) This decision is based on the fact that the MDCC data are cleaner, shorter and therefore easier to learn that those in Common Voice zh-HK.

AttributeError: module 'TTS.tts.datasets' has no attribute 'mdcc'

I need to implement a method call mdcc in TTS/tts/datasets/formatters.py

2024-9-12

Implemented TTS/tts/datasets/formatters.py

got following error:

  File "/home/hgneng/code/hgneng/TTS/TTS/tts/utils/text/tokenizer.py", line 206, in init_from_config
    raise ValueError(
ValueError: No phonemizer found for language yue-cn.
                            You may need to install a third party library for this language.

And I also need to take a look at multi-speaker training.

2024-9-13

For multi-speaker, we need to implement SpeakerManager.

Added code to TTS/tts/utils/text/tokenizer.py to support yue-cn

Got following error:

  File "/home/hgneng/code/hgneng/TTS/TTS/tts/models/tacotron2.py", line 386, in _create_logs
    pred_spec = postnet_outputs[0].data.cpu().numpy()
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Got unsupported ScalarType BFloat16

Need to upload data and code to https://platform.virtaicloud.com/ to run.

P.S. 当ibus中文输入法无法使用的时候，可以通过下面方法重启：

$ ibus-daemon -drx
$ ibus restart // optional

2024-9-14

  1. Setup an environment with Pyhon 3.11, cuda >= 2.1
  2. setup mdcc-dataset link
  3. edit run.sh to restore some one time logic
  4. install dependencies: gemini/code/TTS# pip install .[all,dev]
  5. It's very slow to generate scale_stats.npy on virtualcloud, generate it locally and upload it.

I should fix following error:

当我修改字符集合配置，重启环境运行后遇到以下错误。这个问题和网络有关，多试几次可能就可以了。

2024-9-18

start a machine and pip install . but it seems try to download all versions of every packages that make it never finish. Don't know why. try again tomorrow.

2024-9-19

After changing to another machine and change pip repo to tsinghua, it works again. However, the traing time of one epch increase from 20 minutes to 2 hours.

After realizing not using GPU, change run.sh and run again. It is stuck at

> DataLoader initialization

| > Number of instances : 65120

2024-9-20

The process stop after 2 hours because phoneme_cache is incomplete. It's related to scale_stats.npy. I need to upload it from local. The virtual machine's disk is very slow. Large quantity of files should be processed locally.

Network timeout issue resists. modify the timeout can solve it:

Next time, upload dataset.tar and untar it to /tmp/ which should work around data disk slow issue.

2024-9-24

start a new machine with pytorch 2.2:

  1. Change pip repo: pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
  2. clone code: git clone https://github.com/hgneng/TTS.git
  3. install deps: pip install -e .[all,dev]
  4. copy dataset: cp -r /gemini/data-2/mdcc-dataset /tmp/
  5. link dataset: cd /gemini/code/TTS/recipes/mdcc/tacotron2-DDC/ && ln -sf /tmp/mdcc-dataset
  6. run training: cd /gemini/code/TTS && bash recipes/mdcc/tacotron2-DDC/run.sh

For error of  "assert len(out_dict["token_ids"]) > 0":

  1. don't install TTS. pip install -e .[all,dev]
  2. add debug like https://github.com/coqui-ai/TTS/issues/1624
  3. remove item from csv: 447_1804052037_72795_743.7_744.36 (keep fit)
  4. TODO: clean all items that has no Chinese characters in csv file.

2024-9-25

map all unknown character/phoneme to "v" to fix error of  "assert len(out_dict["token_ids"]) > 0".

It starts training. CPU = 400%/400%, MEM=12G/12G, GPU=20%-40%/100%, GPU_MEM=1.5G/6G

TODO: although we can train now. English text and audio should be do harm to the training. I should remove it in future when improving the quality. Following code can detect whether a file contains Chinese:

grep -P "[\x{4E00}-\x{9FFF}]" <file>

Maybe this is not enough. We should also detect whether a file contains characters other than Chinese and filter them out.

Change transformers>=4.33.0 to transformers>=4.45.1 can prevent pip tries to download too many version information files and significantly speed up pip install. Remove unnecessary dependencies also helps.

2024-10-11

According to https://docs.coqui.ai/en/stable/training_a_model.html#multi-speaker-training , We need to config SpeakerManager. We should label speaker for the database

So we may be better synthesized training data from a good TTS for test. Then record data of ourselves.

To make debug faster, I decrease the training size. 

The error or invalid size is caused by gradual_training in config. According to https://github.com/coqui-ai/TTS/issues/370#issuecomment-796887391 It may imply that I should not use gradual_training here.

After remove gradual_training, training can go on.

Training stop after 10 epoch. It seems caused by image generation.

It takes about 10 days to train the data. I'm going to learn how to check progress in Tensorboard. It seems that file events.out.tfevents.1728968264.gjob-dev-501230719612473344-taskrole1-0.18959.0 within log folder is data file for Tensorboard. Tensorboard need to be setup when create virtaicloud project. I have to wait next training. I only need to link output file dir to /gemini/output. It will work.

virtual machine crashed at EPOCH: 411/1000. The model is not recognizable at all. Need to restore training.

New init steps:

  1. clone code: git clone https://github.com/hgneng/TTS.git
  2. install deps: cd TTS && pip install -e .[all,dev]
  3. copy dataset: cd /gemini/data-1/ && time tar xvf mdcc-dataset.tar -C /tmp/
  4. cp /gemini/code/TTS/recipes/mdcc/tacotron2-DDC/train.csv /tmp/mdcc-dataset/
  5. cp /gemini/code/TTS/recipes/mdcc/tacotron2-DDC/valid.csv /tmp/mdcc-dataset/
  6. link dataset: cd /gemini/code/TTS/recipes/mdcc/tacotron2-DDC/ && ln -sf /tmp/mdcc-dataset
  7. run training: cd /gemini/code/TTS && time bash recipes/mdcc/tacotron2-DDC/run.sh | tee out

我已经在debian上安装了这个TTS 请问如何调用，谢谢

有没有可能基于这个TTS开发一个orca可以调用的版本呢

这个还不支持中文吗，有没有可能让他支持中文呢

将句号作为显式的终止符，在短文本后面人为加上句号，就不会出现意外的颤音了。比如
tts.tts_to_file("你好。")
