How to use
Download all files from this repository to the device
1. PrePare
1.1 Copy this project to AX650 Board
1.2 Prepare Dependencies
Running HTTP Tokenizer Server and Processing Prompt Speech require these Python packages. If you run these two step on a PC, install them on the PC.
pip3 install -r scripts/requirements.txt
2. Start HTTP Tokenizer Server
cd scripts
python CosyVoice3_tokenizer.py --host {your host} --port {your port}
3. Run on Axera Device
There are 2 kinds of device, AX650 Board , AXCL aarch64 Board and AXCL x86 Board.
3.1 Run on AX650 Board
-
Moidfy the HTTP host in
run_ax650.sh. -

Or run on AX650 Board with Gradio GUI
- Start server
bash run_api_ax650.sh
- Start Gradio GUI
python scripts/gradio_demo.py
3.2 Run on AXCL aarch64 Board
bash run_axcl_aarch64.sh
Or run on AXCL aarch64 Board with Gradio GUI
- Start server
bash run_api_axcl_aarch64.sh
- Start Gradio GUI
python scripts/gradio_demo.py
-
Open the page from a browser
The page url is :https://{your device ip}:7860
Note that you need to run these two commands in the project root directory.
3.3 Run on AXCL x86 Board
bash run_axcl_x86.sh
Or run on AXCL aarch64 Board with Gradio GUI
- Start server
bash run_api_axcl_x86.sh
- Start Gradio GUI

The page url is :https://{your device ip}:7860
Note that you need to run these two commands in the project root directory.
Optional. Process Prompt Speech
If you want to replicate a specific sound, do this step.
You can use audio in asset/ .
(1). Downlaod wetext
pip3 install modelscope
modelscope download --model pengzhendong/wetext --local_dir pengzhendong/wetext
(2). Process Prompt Speech
Example:
python3 scripts/process_prompt.py --prompt_text asset/zh_man1.txt --prompt_speech asset/zh_man1.wav --output zh_man1
Pass parameters according to the actual situation.
python3 scripts/process_prompt.py -h
usage: process_prompt.py [-h] [--model_dir MODEL_DIR] [--wetext_dir WETEXT_DIR] [--sample_rate SAMPLE_RATE] [--prompt_text PROMPT_TEXT] [--prompt_speech PROMPT_SPEECH]
[--output OUTPUT]
options:
-h, --help show this help message and exit
--model_dir MODEL_DIR
tokenizer configuration directionary
--wetext_dir WETEXT_DIR
path to wetext
--sample_rate SAMPLE_RATE
Sampling rate for prompt audio
--prompt_text PROMPT_TEXT
The text content of the prompt(reference) audio. Text or file path.
--prompt_speech PROMPT_SPEECH
The path to prompt(reference) audio.
--output OUTPUT Output data storage directory
After executing the above command, files like the following will be generated:
flow_embedding.txt
flow_prompt_speech_token.txt
llm_embedding.txt
llm_prompt_speech_token.txt
prompt_speech_feat.txt
prompt_text.txt
When you run run_ax650.sh, pass the output path here to the prompt_files parameter of the run_ax650.sh script.
