Accuracy backed by open-source benchmark

Evaluate the accuracy of transcription software transparently

Compare the accuracy of transcription engines transparently. The open-source speech-to-text benchmark shows how Cheetah Streaming Speech-to-Text performs compared to the most popular transcription engines.

Improved accuracy with model adaptation

Boost the accuracy of Cheetah Streaming Speech-to-Text with customization

Improve the Cheetah Streaming Speech-to-Text accuracy further by adding application-specific vocabulary and boosting keywords on the no-code Picovoice Console platform.

Speech-to-text APIs transfer voice input to the cloud to transcribe it into text, creating privacy, and reliability issues and additional costs.

Real-time transcription on any platform

Deploy Cheetah Streaming Speech-to-Text on any platform

Offer seamless real-time transcription experiences across platforms without worrying about future expansions. Cheetah Streaming Speech-to-Text processes voice data within web browsers, on devices, mobile apps, on-prem, and even in the public cloud.

Guaranteed response time

Generate real-time transcripts with no network delays

Let your product reach its full potential without delay. Real-time transcription APIs send voice data to the vendor cloud, making it technically impossible to achieve on-device performance.

Design with privacy in mind

Ensure voice data and transcript privacy and security

Better safe than sorry. Sharing users’ data with real-time transcription API providers jeopardizes user privacy and trust. The easiest way to comply with GDPR, CCPA, HIPAA, or any other existing or upcoming regulations and earn users’ trust is not to share.
