Transcription Quality & Accuracy Issues
Common issues and solutions
Poor Audio Quality Results
Cause: Background Noise
Traffic, music, wind, or multiple conversations can confuse the AI transcription engine.
Solution 1: Clean Audio Before Upload
Use noise reduction tools in Audacity or Adobe Audition to remove background noise before uploading.
Solution 2: Use Context Prompt
In upload settings → Advanced → Context/Prompt, add keywords and terminology that appear in your recording to improve accuracy.
Solution 3: Re-record with Better Equipment
Use a quality microphone closer to the speaker. Phone recordings often have poor quality.
Wrong Language Detected
Solution: Manual Language Selection
Don't use "Auto-detect". Explicitly select your language in upload settings → Language.
Supported Languages
English, Spanish, French, German, Italian, Portuguese, Russian, Chinese, Japanese, Korean, Arabic, Hindi, and 50+ more.
For Mixed Language Audio
Choose the primary language spoken (the language used most frequently in the recording).
Technical Terms Not Recognized
Use Context Prompt (PRO+)
Add a list of technical terms, acronyms, and proper nouns in upload settings → Advanced → Context/Prompt.
Example Prompt
For medical recording: "Terms used: MRI, CT scan, diagnosis, hypertension, metformin, patient chart, Dr. Johnson"
Edit After Transcription
Use the inline editor to correct misrecognized terms manually. Click any word to edit.
Speaker Identification Errors (PRO+)
Cause: Similar Voices
If speakers sound similar, the AI may struggle to distinguish them accurately.
Solution 1: Specify Number of Speakers
In upload settings → Speaker Diarization → Number of Speakers, enter the exact count. This improves accuracy significantly.
Solution 2: Rename Speakers After
Click speaker labels (SPEAKER_00, SPEAKER_01) to rename them to actual names for clarity.
Better Audio Separation
For future recordings, use separate microphones or ensure speakers take turns speaking (minimize overlapping speech).
