The accuracy of voice transcription and recognition are the cornerstones of Otter.
How does Otter transcribe speech-to-text?
Otter is cloud-based and 100% AI-powered (no human transcribers involved). Our speech-to-text engine supports English, speaker-independent transcription, and works out of the box without requiring hours of personalized training with your voice. Our speaker identification algorithm is powered by advanced machine learning that distinguishes and learns from just a few paragraphs you tag to create a voiceprint for each speaker. The result is a legible, speaker-labeled transcript with synchronized audio and text.

How to increase speech accuracy
To increase the accuracy of Otter's transcription, follow these best practices:
- Use an external microphone or headset, rather than your computer or device's built-in microphone.
- Place the microphone within three feet from the person speaking.
- Try to minimize background noise.
- Avoid overlapping dialog where speakers talk over one another.
- Speak clearly and naturally, at your normal conversational tone and pace.
- Customize Otter's vocabulary to enhance the quality and accuracy of certain words, names, acronyms, jargon, etc.
How does Otter handle filler words such as "um"?
Fillers, interjections, and hesitation markers are sounds such as "hmm" or "um" that is spoken in conversation as a pause for thought. These sounds or words are programmatically ignored, including if they were to be added to your custom vocabulary.
