docs(realtime-stt): drop the client-set draft interval by liujiahua123123 · Pull Request #287 · fishaudio/docs

liujiahua123123 · 2026-10-25T11:19:19Z

Summary

The realtime STT server now decides how often drafts are sent: a client's results.draft_interval_ms is accepted (no error, any value) but ignored, and session_started / configured no longer echo it.

This removes everything that offered a client-set draft interval:

asr-realtime.mdx: the results.draft_interval_ms row of the config table, and "sent at most every draft_interval_ms" in the draft section ("Drafts are best effort and only sent with results.drafts: true").
asyncapi-asr-realtime.yml: the draft_interval_ms property of AsrResults (config) and AsrResultsUpdate (configure), the field in the session_started example, and "at most every draft_interval_ms" in the draft message description.

Unchanged: the Limits row "Drafts: At most every 250 ms", which stays true.

Pairs with fishaudio/realtime-asr#29 (PROTOCOL v0.2.17). Merging this first is harmless: a client that still sends the field keeps working.

Summary by CodeRabbit

Documentation
- Removed draft_interval_ms from the realtime ASR configuration examples and reference schemas.
- Updated draft documentation to no longer describe a configurable interval. It continues to note that draft results are best effort and may pause during long background sounds, and explains how to interpret tentative, stable, and final transcript text.

The server now decides the draft cadence: results.draft_interval_ms is accepted and ignored, and session_started no longer echoes it. Remove the config row, the schema properties (config and configure), the session_started example field, and "at most every draft_interval_ms" from the draft descriptions. The limits row (at most every 250 ms) stays true. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Walkthrough

The realtime ASR reference removes the draft_interval_ms configuration from its schema and endpoint documentation. It also removes claims that draft delivery follows a configured maximum frequency. Other draft guidance remains.

Changes: Realtime ASR draft interval

Layer / File(s)	Summary
Remove draft interval configuration and claims `api-reference/asyncapi-asr-realtime.yml`, `api-reference/endpoint/websocket/asr-realtime.mdx`	The schemas, session example, and endpoint documentation no longer include `draft_interval_ms` or describe a configured draft frequency. Guidance on stable and tentative text, committed transcripts, and best-effort drafts remains.

Document the draft_interval_ms compatibility exception.

Removing draft_interval_ms from AsrResults and AsrResultsUpdate leaves the field undocumented. The endpoint reference treats any unknown field as invalid_config, which closes the connection with 4400 (api-reference/endpoint/websocket/asr-realtime.mdx, line 123). Its configure rule rejects unknown fields as well (line 202). A client that still sends results.draft_interval_ms therefore matches the documented rejection rule. The PR states that the server accepts and ignores this field for existing clients. The schema and endpoint docs need to state that exception, or they describe behavior that conflicts with the stated compatibility.

Add the exception at the object level in both schemas, and name the same exception in the endpoint unknown-field rules for both config and configure.

Suggested schema note

AsrResults: type: object + description: | + `draft_interval_ms` is no longer defined. Existing clients may still send it; the server accepts and ignores it. properties:
