Custom Vocabulary for Technical ASR

Highly accurate transcription (98%+) for specialized, technical audio content.

$500 - $5,000 one-time training + per minute cost3-5 days for training and tuning

The Problem

Need to transcribe medical or legal audio where standard ASR models fail due to highly specific, domain-related jargon.

Expected Outcome

Highly accurate transcription (98%+) for specialized, technical audio content.

Tool Chain

Implementation Steps

  1. 1

    Domain Data Collection

    Collect a corpus of 10-20 hours of relevant audio and transcripts (e.g., past medical consultations, legal proceedings).

  2. 2

    Custom Language Model Training

    Use the custom data to train an augmented ASR model, significantly improving accuracy on domain-specific terms.

    IBM Watson Speech to Text
  3. 3

    Real-Time Transcription and Testing

    Stream the target audio for real-time transcription, testing the new model's accuracy against a control group.

  4. 4

    Feedback Loop

    Implement a human-in-the-loop QA step to correct errors and feed them back to the training model.

Alternatives

Step 2

Similar robust customization, better integration with Azure tools.

Cost Impact: N/A

Cheaper in the long run (self-hosted), but requires significant MLOps expertise.

Cost Impact: -50%
