Model Studio Qwen TTS Realtime

Use realtime TTS models for low-latency streaming speech output.

Critical model names

Use one of these exact model strings:

```
qwen3-tts-flash-realtime
```
```
qwen3-tts-instruct-flash-realtime
```

Prerequisites

Install SDK in a virtual environment:

bash

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.realtime)

Request

```
text
```
(string, required)
```
voice
```
(string, required)
```
instruction
```
(string, optional)
```
sample_rate
```
(int, optional)

Response

```
audio_base64_pcm_chunks
```
(array<string>)
```
sample_rate
```
(int)
```
finish_reason
```
(string)

Operational guidance

Use websocket or streaming endpoint for realtime mode.
Keep each utterance short for lower latency.
For instruction models, keep instruction explicit and concise.
Some SDK/runtime combinations may reject realtime model calls over
```
MultiModalConversation
```
; use the probe script below to verify compatibility.

Local demo script

Use the probe script to verify realtime compatibility in your current SDK/runtime, and optionally fallback to a non-realtime model for immediate output:

bash

.venv/bin/python skills/ai/audio/alicloud-ai-audio-tts-realtime/scripts/realtime_tts_demo.py \
  --text "这是一个 realtime 语音演示。" \
  --fallback \
  --output output/ai-audio-tts-realtime/audio/fallback-demo.wav

Strict mode (for CI / gating):

bash

.venv/bin/python skills/ai/audio/alicloud-ai-audio-tts-realtime/scripts/realtime_tts_demo.py \
  --text "realtime health check" \
  --strict

Output location

Default output:
```
output/ai-audio-tts-realtime/audio/
```
Override base dir with
```
OUTPUT_DIR
```
.
