EmotiVoice is a powerful and modern open-source text-to-speech engine that is available to you at no cost. EmotiVoice speaks both English and Chinese, and with over 2000 different voices (refer to the List of Voices for details). The most prominent feature is emotional synthesis, allowing you to create speech with a wide range of emotions, including happy, excited, sad, angry and others.

An easy-to-use web interface is provided. There is also a scripting interface for batch generation of results.

Here are a few samples that EmotiVoice generates:

• Chinese audio sample

• English audio sample

• Fun Chinese English audio sample

Demo

A demo is hosted on Replicate, EmotiVoice.

Quickstart

EmotiVoice Docker image

The easiest way to try EmotiVoice is by running the docker image. You need a machine with a NVidia GPU. If you have not done so, set up NVidia container toolkit by following the instructions for Linux or Windows WSL2. Then EmotiVoice can be run with,

docker run -dp 127.0.0.1:8501:8501 syq163/emoti-voice:latest

The Docker image was updated on January 4th, 2024. If you have an older version, please update it by running the following commands:

docker pull syq163/emoti-voice:latest
docker run -dp 127.0.0.1:8501:8501 -p 127.0.0.1:8000:8000 syq163/emoti-voice:latest

Now open your browser and navigate to http://localhost:8501 to start using EmotiVoice's powerful TTS capabilities.

Starting from this version, the 'OpenAI-compatible-TTS API' is now accessible via http://localhost:8000/.

Full installation

conda create -n EmotiVoice python=3.8 -y
conda activate EmotiVoice
pip install torch torchaudio
pip install numpy numba scipy transformers soundfile yacs g2p_en jieba pypinyin pypinyin_dict
python -m nltk.downloader "averaged_perceptron_tagger_eng"

Prepare model files

We recommend that users refer to the wiki page How to download the pretrained model files if they encounter any issues.

git lfs install
git lfs clone https://huggingface.co/WangZeJun/simbert-base-chinese WangZeJun/simbert-base-chinese

or, you can run:

git clone https://www.modelscope.cn/syq163/WangZeJun.git

Inference

1. You can download the pretrained models by simply running the following command:

git clone https://www.modelscope.cn/syq163/outputs.git

1. The inference text format is <speaker>|<style_prompt/emotion_prompt/content>|<phoneme>|<content>.

• inference text example: 8051|Happy|<sos/eos> [IH0] [M] [AA1] [T] engsp4 [V] [OY1] [S] engsp4 [AH0] engsp1 [M] [AH1] [L] [T] [IY0] engsp4 [V] [OY1] [S] engsp1 [AE1] [N] [D] engsp1 [P] [R] [AA1] [M] [P] [T] engsp4 [K] [AH0] [N] [T] [R] [OW1] [L] [D] engsp1 [T] [IY1] engsp4 [T] [IY1] engsp4 [EH1] [S] engsp1 [EH1] [N] [JH] [AH0] [N] . <sos/eos>|Emoti-Voice - a Multi-Voice and Prompt-Controlled T-T-S Engine.

1. You can get phonemes by python frontend.py data/my_text.txt > data/my_text_for_tts.txt.

2. Then run:

TEXT=data/inference/text
python inference_am_vocoder_joint.py \
--logdir prompt_tts_open_source_joint \
--config_folder config/joint \
--checkpoint g_00140000 \
--test_file $TEXT

the synthesized speech is under outputs/prompt_tts_open_source_joint/test_audio.

1. Or if you just want to use the interactive TTS demo page, run:

pip install streamlit
streamlit run demo_page.py

OpenAI-compatible-TTS API

Thanks to @lewangdev for adding an OpenAI compatible API #60. To set it up, use the following command:

pip install fastapi pydub uvicorn[standard] pyrubberband
uvicorn openaiapi:app --reload

Training

Voice Cloning with your personal data has been released on December 13th, 2023.

Roadmap & Future work

• Our future plan can be found in the ROADMAP file.
• The current implementation focuses on emotion/style control by prompts. It uses only pitch, speed, energy, and emotion as style factors, and does not use gender. But it is not complicated to change it to style/timbre control.
• Suggestions are welcome. You can file issues or @ydopensource on twitter.
