Watson Speech services on Cloud Pak for Data as a Service


The Watson Speech services for IBM Cloud Pak® for Data offer speech recognition and speech synthesis capabilities for your applications:

  • Watson Speech to Text for IBM Cloud Pak for Data 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 for IBM Cloud Pak for Data 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.
