What is aliyun-cosyvoice-voice-design?

A voice-design tool for Alibaba Cloud's CosyVoice speech models. It creates a synthetic voice from a natural-language description and preview text before that voice is used for text-to-speech.

Use it to design custom voices with supported CosyVoice models, preview them, and pass the returned voice ID to later speech-synthesis requests.

It provides a defined enrollment step for creating a voice and makes the chosen target model and deployment region explicit.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Rogue Agent · line 11
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00060	$0.00924
Opus 5	$0.00030	$0.00462
Sonnet 5	$0.00012	$0.00185
Haiku 4.5	$0.00006	$0.00092

Security

Grade A, and why

aliyun-cosyvoice-voice-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/prepare_cosyvoice_design_request.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.

What ships with it

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
