The plain transcribe command still used chunk overlap speaker matching,
so users had to discover a model flag or supply a known speaker count to
get the improved voice comparison behavior.
Enable OpenRouter voice comparison with automatic speaker counting for
normal text and SRT invocations. Keep --speakers and --speaker-model as
optional overrides, and let --no-diarization disable both provider labels
and voice comparison. Make the basic command the documentation entry point
and clarify the defaults in CLI help and repository guidance.
Cover bare invocations across one and multiple uploads, default SRT,
optional count constraints, opt-out ordering, and atomic output when the
default comparison fails.
Test Plan:
- python3 -B -m unittest -v: all 85 tests passed.
- bash -n transcribe: passed.
- git diff --cached --check: passed.
- Tests use real audio encoding with fake provider responses. Live voice
accuracy remains unverified; no live API request was made for this change.
Short chunk overlaps often contain only one participant, so returning
speakers receive new transcript IDs. MAI can also split one voice into
several IDs within a single request, which overlap stitching cannot fix.
Add an opt-in audio comparison pass: --speakers N selects Gemini 3.8 Flash
with a known count, and --speaker-model allows another compatible model.
Keep request-local identities separate, select up to three clean excerpts
per ID, and compare all excerpts in one OpenRouter request. Gemini uses
Google AI Studio because the Vertex backend limits prompts to one audio
file. No local model or extra Python dependency is required.
Only reconcile identities whose sample assignments agree. Preserve
uncertain identities separately, reject incomplete or malformed replies,
and retain the original words and timestamps. Bound sample count and
request size, clip sampling to the real audio duration, and extend worker
cleanup and buffered output to the comparison step. Document the sampled
method's limitations and additional provider request.
Test Plan:
- python3 -B -m unittest -v: all 82 tests passed, including real MP3
encoding with fake transcription/comparison responses and cancellation.
- bash -n transcribe: passed.
- git diff --cached --check: passed.
- Live API and voice accuracy unverified: this workspace could not access
the configured 1Password credential. Mocked responses prove pipeline
behavior, not model accuracy on the supplied recording.
Render transcript-wide speaker numbers instead of exposing upload chunks in
reader-facing headers. Reconcile adjacent requests using at least two
unambiguous word-and-time matches in their shared audio, including when
provider speaker IDs change between requests. Reject conflicting mappings
and never treat matching numeric provider IDs as identity evidence.
Assign fresh IDs where continuity cannot be established and report that
uncertainty on stderr. Number only speakers retained after overlap trimming.
Document that overlap matching cannot identify a returning speaker who was
absent from the overlap, and add the reader-facing boundary to AGENTS.md.
Test Plan:
- python3 -B -m unittest -v: all 46 tests passed, including swapped IDs,
ambiguous evidence, continuity across three requests, and plain headers.
- git diff --cached --check: passed.
- Tests use synthetic speaker labels; live diarization accuracy was not
verified because provider credentials are unavailable in this environment.
Record the repository policy that agents must commit completed, validated
work without waiting for an additional user request. Require focused
commits, relevant checks, explicit validation limits, and post-commit
verification while excluding recordings, transcripts, and unrelated files.
Document the CLI and helper responsibilities and preserve ordered output,
request-local speaker IDs, and all-or-nothing stdout as project invariants.
Test Plan:
- Reviewed AGENTS.md against the requested automatic-commit policy and the
current repository layout.
- git diff --cached --check: passed.
