Description

The Watson Speech services offer speech recognition and speech synthesis capabilities for your applications:

  • Watson Speech to Text transcribes written text from spoken audio. The service leverages machine learning to combine knowledge of grammar, language structure, and the composition of audio and voice signals to accurately transcribe the human voice. It continuously updates and refines its transcription as it receives more speech audio. The service is ideal for applications that need to extract high-quality speech transcripts for use cases such as call centers, custom care, agent assistance, and similar solutions.

    For more information about the service, see About Watson Speech to Text.

  • Watson Text to Speech synthesizes natural-sounding speech from written text. The service streams the results back to the client with minimal delay. The service is appropriate for voice-driven and screenless applications, where audio is the preferred method of output.

    For more information about the service, see About Watson Text to Speech.

You can customize the Watson Speech services to suit your language and application needs. Both services offer HTTP and WebSocket programming interfaces that make them suitable for any application that produces or accepts audio.
