Week of January 06 - January 13, 2026

Transcript

Welcome to Buzz Transcription's weekly developer recap for January 6th through 13th, 2026.

Two PRs merged and two additional commits this week.

**Bug Fixes**

Rob Siera resolved two critical issues in speaker identification functionality. The first fix addresses chunk size errors that occurred when processing long transcriptions. The speaker identification system was attempting to process punctuation model predictions in batches that were too large, triggering assertion errors. Siera implemented batch processing with fallback logic that switches to smaller chunks if initial processing fails. The solution adds 65 lines of code to the speaker identification widget and includes 80 lines of new test coverage.

The second fix resolves missing spaces after punctuation in transcribed text. The issue stemmed from how transcript segments were joined for whisperx alignment. Segments were being concatenated without spaces using Python's join method, producing awkward text like "ok.Yes" instead of "ok. Yes." The fix changes the joining method to preserve proper sentence boundaries with spaces.

Both fixes target the transcription viewer's speaker identification widget, addressing issues reported by users experiencing problems with long-form content processing and text formatting quality.

**Testing**

All changes include corresponding test updates. The chunk size fix adds comprehensive test coverage for batch processing scenarios and error handling. The punctuation spacing fix includes test validation for proper segment joining.

**Impact**

These fixes directly improve transcription quality for users working with lengthy audio files and ensure readable output formatting. The batch processing enhancement should eliminate crashes during speaker identification on extended recordings.

Next week's focus will likely continue addressing user-reported transcription quality issues as the team works through the current issue backlog.

That wraps this week's Buzz Transcription development update.
