Meeting Transcription Accuracy: What Affects It and How to Improve It

Meeting transcription accuracy is not a fixed quality score — it varies significantly based on conditions that teams can actually control. Understanding what affects it lets you improve results without switching tools. MeetOye (meetoye.com) processes transcription through Oya with configurations designed to improve accuracy in common meeting scenarios.

The main variables

Audio input quality

This is the single largest factor. A dedicated headset or USB microphone produces dramatically better audio than a laptop's built-in microphone in anything less than a quiet room. The difference in transcription accuracy between a good headset and a laptop mic in a noisy environment can be 20-30 percentage points.

What this means practically: invest in microphone quality before evaluating transcription quality. A poor mic is a ceiling on accuracy that no amount of AI sophistication can overcome.

Background noise

HVAC systems, keyboard noise, ambient office noise, and nearby conversations all introduce transcription errors. Noise cancellation — whether hardware (isolating headset) or software (noise cancellation built into the meeting platform) — reduces error rates materially.

Speaker characteristics

ASR models are trained on large distributions of speech data. Speakers with less common accents, unusually fast speech, or heavy technical jargon may see higher error rates than speakers whose patterns match the model's training distribution more closely.

Language configuration

If the transcription system auto-detects language and the speaker has an accent from a non-English language background, the system may occasionally make incorrect language-detection decisions. Setting the language explicitly (rather than auto-detect) improves accuracy for non-native English speakers.

Domain terminology

Technical terms, product names, abbreviations, and proper nouns are more likely to be transcribed incorrectly than common vocabulary. Some transcription systems support custom vocabulary or domain tuning for this reason.

Practical steps to improve accuracy

1. Use a headset or USB microphone — the single highest-impact change
2. Enable software noise cancellation in your meeting platform
3. Speak at a moderate pace when sharing important information or decisions
4. Set the language explicitly rather than relying on auto-detection
5. Reduce background noise before important calls (close doors, mute when not speaking)

How MeetOye handles accuracy

MeetOye's meeting transcription uses English-optimized models when the meeting language is set to English, and applies voice activity detection to filter out non-speech segments. Speaker diarization separates audio by participant, which reduces cross-talk errors. The quality of the transcript directly affects the quality of the recap and action item extraction that Oya generates afterward.
