2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Use when designing custom voices with Alibaba Cloud Model Studio CosyVoice customization models, especially cosyvoice-v3.5-plus or cosyvoice-v3.5-flash, from a voice prompt plus preview text before using the returned voice_id in TTS.

Model Studio CosyVoice Voice Design

Use the CosyVoice voice enrollment API to create designed voices from a natural-language voice description.

Critical model names

Use model="voice-enrollment" and one of these target_model values:

cosyvoice-v3.5-plus
cosyvoice-v3.5-flash
cosyvoice-v3-plus
cosyvoice-v3-flash

Recommended default in this repo:

target_model="cosyvoice-v3.5-plus"

Region and compatibility

cosyvoice-v3.5-plus and cosyvoice-v3.5-flash are available only in China mainland deployment mode (Beijing endpoint).
In international deployment mode (Singapore endpoint), cosyvoice-v3-plus and cosyvoice-v3-flash do not support voice clone/design.
The target_model must match the later speech synthesis model.

Endpoint

Domestic: https://dashscope.aliyuncs.com/api/v1/services/audio/tts/customization
International: https://dashscope-intl.aliyuncs.com/api/v1/services/audio/tts/customization

Prerequisites

Set DASHSCOPE_API_KEY in your environment, or add dashscope_api_key to ~/.alibabacloud/credentials.

Normalized interface (cosyvoice.voice_design)

Request

model (string, optional): fixed to voice-enrollment
target_model (string, optional): default cosyvoice-v3.5-plus
prefix (string, required): letters/digits only, max 10 chars
voice_prompt (string, required): max 500 chars, Chinese or English only
preview_text (string, required): max 200 chars, Chinese or English
language_hints (array[string], optional): zh or en, and should match preview_text
sample_rate (int, optional): e.g. 24000
response_format (string, optional): e.g. wav

Response

voice_id (string)
request_id (string)
status (string, optional)

Operational guidance

Keep voice_prompt concrete: timbre, age range, pace, emotion, articulation, and scenario.
If language_hints is used, it should match the language of preview_text.
Designed voice names include a -vd- marker in the generated backend naming convention.

Local helper script

Prepare a normalized request JSON:

python skills/ai/audio/alicloud-ai-audio-cosyvoice-voice-design/scripts/prepare_cosyvoice_design_request.py \
  --target-model cosyvoice-v3.5-plus \
  --prefix announcer \
  --voice-prompt "沉稳的中年男性播音员，低沉有磁性，语速平稳，吐字清晰。" \
  --preview-text "各位听众朋友，大家好，欢迎收听晚间新闻。" \
  --language-hint zh

Validation

mkdir -p output/alicloud-ai-audio-cosyvoice-voice-design
for f in skills/ai/audio/alicloud-ai-audio-cosyvoice-voice-design/scripts/*.py; do
  python3 -m py_compile "$f"
done
echo "py_compile_ok" > output/alicloud-ai-audio-cosyvoice-voice-design/validate.txt

Pass criteria: command exits 0 and output/alicloud-ai-audio-cosyvoice-voice-design/validate.txt is generated.

Output And Evidence

Save artifacts, command outputs, and API response summaries under output/alicloud-ai-audio-cosyvoice-voice-design/.
Include target_model, prefix, voice_prompt, and preview_text in the evidence file.
