Cleft is currently optimized for US English, using the Whisper model for voice recognition. However, we’ve enabled early access to additional languages based on user requests.

  • Cleft supports 50+ languages that have reached a benchmark of < 50% word error rate (WER) for speech-to-text accuracy.
  • The Whisper model has been trained on 98 languages in total.
  • We’re continuously improving language support based on customer feedback.

As a small bootstrapped team, we prioritize new language support based on customer requests. If you’d like to see better support for your preferred language, please reach out to us!

​
How to Use Multiple Languages

  1. Open the Language Settings in the Cleft app
  2. Select your desired transcription(input) language or choose auto-detect
