Available APIs
Qwen3-ASR is available through two distinct DashScope APIs, each suited to a different use case:Real-time API
Low-latency, streaming speech recognition designed for live audio feeds. Ideal for applications like live captioning, voice assistants, and real-time transcription of calls or meetings.
FileTrans API
Asynchronous, file-based transcription for pre-recorded audio. Suited for batch processing, podcast transcription, and workflows where latency is not a concern.
API Documentation
Full parameter references, authentication guides, and code samples are available in the official DashScope documentation. Choose the link that matches your region:| API | Documentation (Mainland China) | Documentation (International) |
|---|---|---|
| Real-time API | help.aliyun.com (CN) | alibabacloud.com (EN) |
| FileTrans API | help.aliyun.com (CN) | alibabacloud.com (EN) |
Choosing the Right API
Use the Real-time API when:- You need transcription output within milliseconds of speech.
- Your audio source is a microphone stream, phone call, or live broadcast.
- Your application needs to react to transcription results as they are produced.
- You have pre-recorded audio files to transcribe in bulk.
- Turnaround time of seconds to minutes is acceptable.
- You want a simple submit-and-poll workflow without managing a persistent connection.
The DashScope API is a commercial cloud service managed by Alibaba Cloud. It is entirely separate from the self-hosted deployment options described in the rest of this documentation. Using the API requires a DashScope account and API key — no GPU hardware on your end is needed.
