Model Studio Qwen TTS Voice Design

Use voice design models to create controllable synthetic voices from natural language descriptions.

Critical model names

Use one of these exact model strings:

• qwen3-tts-vd-2026-01-26

• qwen3-tts-vd-realtime-2026-01-15

Prerequisites

• Install SDK in a virtual environment:

python3 -m venv .venv . .venv/bin/activate python -m pip install dashscope

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

Normalized interface (tts.voice_design)

Request

• voice_prompt (string, required) target voice description

• text (string, required)

• stream (bool, optional)

Response

• audio_url (string) or streaming PCM chunks

• voice_id (string)

• request_id (string)

Operational guidance

• Write voice prompts with tone, pace, emotion, and timbre constraints.

• Build a reusable voice prompt library for product consistency.

• Validate generated voice in short utterances before long scripts.

Local helper script

Prepare a normalized request JSON and validate response schema:

.venv/bin/python skills/ai/audio/alicloud-ai-audio-tts-voice-design/scripts/prepare_voice_design_request.py
--voice-prompt "A warm female host voice, clear articulation, medium pace"
--text "This is a voice-design demo"

Output location

• Default output: output/ai-audio-tts-voice-design/audio/

• Override base dir with OUTPUT_DIR .

Validation

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

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

Output And Evidence

• Save artifacts, command outputs, and API response summaries under output/alicloud-ai-audio-tts-voice-design/ .

• Include key parameters (region/resource id/time range) in evidence files for reproducibility.

Workflow

• Confirm user intent, region, identifiers, and whether the operation is read-only or mutating.

• Run one minimal read-only query first to verify connectivity and permissions.

• Execute the target operation with explicit parameters and bounded scope.

• Verify results and save output/evidence files.
