The Californer/10332275

REDWOOD CITY, Calif. - Californer -- BrassTranscripts announces the availability of professional multi-speaker transcription powered by WhisperX large-v3 with automatic speaker identification. The service combines OpenAI's latest Whisper model with Pyannote 3.1 speaker diarization technology to delivertranscripts with automatic speaker labels across 99+ languages.

Automatic Speaker Identification for Professional Use

Speaker diarization—the process of determining "who said what" in an audio recording—runs automatically on all BrassTranscripts uploads. The system analyzes voice characteristics including pitch, tone, and speaking patterns to distinguish between speakers and assign labels to each spoken segment with timestamps. No additional configuration or manual tagging is required.

Every transcript includes speaker labels automatically in all four output formats: TXT for clean text documentation, SRT for video subtitles, VTT for web captions, and JSON for structured data applications. Processing completes in 1-3 minutes per hour of audio, providing fast turnaround times for time-sensitive projects.
