Where indicated, the format that you specify must include the sampling rate and can `"Content-Type: application/octet-stream"`.) (With the `curl` command, you can specify either `"Content-Type:"` or `application/octet-stream` with the header to have the service automatically detect the format * For all other formats, you can omit the `Content-Type` header or specify Labeled **Required**, you must use the `Content-Type` header with the request to specify theįormat of the audio. The service accepts audio in the following formats (MIME types). `inactivity_timeout` parameter to change the default of 30 seconds. ![]() The service also closes the connection (statusĬode 400) if it detects no speech for `inactivity_timeout` seconds of streaming audio use the (including silence) in any 30-second period. In streaming mode, the serviceĬloses the connection (status code 408) if it does not receive at least 15 seconds of audio `Transfer-Encoding` header to `chunked` to use streaming mode. `-data-binary` option to upload the file for the request.)įor requests to transcribe live audio as it becomes available, you must set the Results to enable interim results, use the WebSocket API. The service automaticallyĭetects the endianness of the incoming audio and, for audio that includes multiple channels,ĭownmixes the audio to one-channel mono during transcoding. Maximum of 100 MB and a minimum of 100 bytes of audio with a request. Sends audio and returns transcription results for a recognition request. Grammars are betaįunctionality for all language models that support language model customization. Production use with all language models that are generally available. Language model customization and acoustic model customization are generally available for Specification that lets you restrict the phrases that the service can recognize. Model customization, the service also supports grammars. Use acoustic modelĬustomization to adapt a base model for the acoustic characteristics of your audio. Use language model customization toĮxpand the vocabulary of a base model with domain-specific terminology. The service also offers two customization interfaces. Service and receive results over a single connection asynchronously. Provides a full-duplex, low-latency communication channel: Clients send requests and audio to the It also supports a WebSocket interface that Representational State Transfer (REST) interfaces. It returns all JSON response content inįor speech recognition, the service supports synchronous and asynchronous HTTP Supports two sampling rates, broadband and narrowband. In addition to basic transcription, the service can produceĭetailed information about many different aspects of the audio. The IBM Watson™ Speech to Text service provides APIs that use IBM's speech-recognitionĬapabilities to produce transcripts of spoken audio. ![]()
