Transcribe Files

Stenox can transcribe audio and video files — not just live dictation. Perfect for meetings, interviews, podcasts, or any recorded content.
File transcription uses your configured transcription provider. For best results with long files, use a cloud provider like DeepGram or Groq.

Provider Considerations

For Short Files (< 5 minutes)

Any provider works well:
  • WhisperKit — Local, private
  • Groq Whisper — Fast, free tier
  • DeepGram — Accurate

For Long Files (> 5 minutes)

Cloud providers recommended:
  • DeepGram — Best for long-form content
  • Groq Whisper — Fast processing
  • AssemblyAI — Good for meetings
WhisperKit can handle long files but processing time increases significantly. For a 30-minute file, expect 10-15 minutes of processing time locally.

Tips for Best Results

Audio Quality

  • Use the highest quality recording available
  • Clear audio with minimal background noise transcribes best
  • Multiple speakers work best with DeepGram or AssemblyAI

File Size

  • Smaller file sizes upload and process faster
  • Consider compressing large files before transcription
  • MP3 is a good balance of quality and size

Language

  • Set the correct language in your Profile settings
  • Use multilingual models for non-English content
  • Auto-detect works but explicit setting is more accurate

AI Enhancement

File transcriptions can be enhanced just like live dictation:
  • Grammar correction — Fix spoken language patterns
  • Punctuation — Add proper punctuation
  • Formatting — Clean up for readability
For meeting transcripts, use a custom prompt like: “Format as meeting notes with bullet points for action items.”

Usage Limits

File transcription counts against your plan limits:

Free5 minutes/day total (including files)

Lifetime PlusUnlimited
Using BYOK providers bypasses Stenox limits. Only your provider’s limits apply.

Troubleshooting

  • Use a cloud provider for faster processing
  • Switch from WhisperKit to Groq or DeepGram
  • For local processing, use base.en instead of small.en
Convert your file to a supported format:
  • Use QuickTime (File → Export As) for video
  • Use online converters for audio
  • MP3 and MP4 are widely compatible
  • Check audio quality in the original file
  • Try a different provider (DeepGram often works best)
  • Set explicit language instead of auto-detect
  • Add technical terms to Vocabulary
  • Compress the file before transcribing
  • Split into smaller segments
  • Use cloud providers for large files
