- New opt-in server flag `--stream-speech` / `INLAY_STREAM_SPEECH=1`. While audio uploads, Silero scores each new second, and once 8 seconds are waiting the server cuts at the next pause at least as long as the speaker's median pause in that stretch. Parakeet recognizes each piece with 4 s of audio before and 2 s after as context, keeping only the piece's own words. On release only the audio after the last cut is left. - Replaying real takes at speaking pace on a Ryzen 5600G (CPU, q8): the wait after release went from 3.9/6.5/10.4/21.7 s to 1.3/1.0/1.2/1.8 s for 37/55/81/148 s takes. Speech detection costs about 4 ms of CPU per second of audio. - Trade-off: pieces lose whole-take context. On 13 real takes about 5% of words differed from a whole-take pass, and hand-checking showed the whole-take pass right more often (mostly names and jargon). Shorter pieces (3–5 s) were worse still, so the flag stays off by default. - The speech helper gains a `speech` request (per-window Silero probabilities) and optional `keepFrom`/`keepUntil` on `transcribe`. Sealed takes get the helper before streamed pieces. Restarts, cancellation, and helper failures fall back to recognizing whatever the pieces did not cover. - `speech.processingSeconds` for a streamed take counts only the wait after release, matching what the app shows.

Abort streamed inference when the stream closes.
When cleanPartial closes a receiving stream, the active advanceStream task continues because both helper calls receive no AbortSignal. SpeechSlot remains busy until the request returns or reaches its timeout. An urgent sealed-take request must wait for that slot, so cancellation can delay recognition of another take.
Add a controller to SpeechStream, abort it in cleanPartial, and pass its signal to both inference calls.

recognize waits for stream.task before submitting the finished take's urgent request. When that task is queued behind other takes' streamed pieces, those pieces run first. Users on a shared server can therefore wait for unfinished recordings before their completed take gets recognized.
Skip or remove queued streaming work when a take seals. Only wait for a piece that has actually started.

processingSeconds misses time spent waiting for the speech slot. waited is measured before transcribe enters that queue, while the helper's returned time counts only recognition. The no-pieces branch also skips the earlier wait for stream.task. Users can see a short processing time after waiting several seconds for another recording.

Summary
On a CPU server the wait after release grows with the take: Parakeet only starts once the recording is sealed, and a whole-take pass gets slower per second as takes get longer. This adds an opt-in
--stream-speechflag (INLAY_STREAM_SPEECH=1) that recognizes finished speech while the take is still uploading, so only the last few seconds are left after release.speechrequest (per-window Silero probabilities) and optionalkeepFrom/keepUntilontranscribe.speech.processingSecondscounts only the wait after release, which is what the app shows.Numbers
Ryzen 5 5600G, CPU, Parakeet v3 q8. Real takes replayed through the HTTP API at speaking pace (0.25 s chunks), old and new image side by side:
Speech detection costs about 4 ms of CPU per second of audio.
Trade-off
Pieces lose whole-take context. Across 13 real takes (accented, spontaneous English) about 5% of words differed from a whole-take pass, ignoring fillers and stutters. Checking the differences by hand, the whole-take pass was right more often, mostly on names and jargon. Shorter pieces were worse (3 s minimum: 7.2%, 5 s: 6.4%) for a few tenths of a second saved, and 15 s of context was no better than 4 s while once dropping a sentence. That is why it is off by default.

Note
Add streaming speech recognition for takes during upload
--stream-speechoption (orINLAY_STREAM_SPEECH=1) starts background speech recognition while a take uploads. The server scores Silero speech probabilities every 32 ms window, detects natural pauses, and commits recognized text pieces at qualifying pauses with 2 seconds of lookahead.detectSpeechrequest type and optionalkeepFrom/keepUntilbounds on transcription, so the engine recognizes full audio but returns only words starting in the kept range (see worker.cpp).SpeechSlotscheduler, so the speech backend runs one task at a time.Macroscope summarized 6f01de4.
The remaining performance and timing-reporting concerns are non-blocking; no blocking merge-safety issue is established.

Summary
Adds opt-in speech recognition while recordings upload.
T-Rex validation blocked
Both real-service checks stopped before recording upload or recognition because the configured Parakeet model file,
ggml-parakeet-tdt-0.6b-v3-f16.bin, was missing. Recording creation returned HTTP 503. The scheduling and timing behaviors could not be exercised.Reviews (1) · Last reviewed commit: "FEATURE: Recognize speech while a take u..." · Reviewed by Greptile
