![]() This script has been created by Daniel Bolanos in order to facilitate and promote the utilization of the IBM Watson Speech To Text service. The IBM Watson Compare and Comply API allows. To see the list of available options type: The IBM Watson Text to Speech WebSocket API service works with Text-to-Speech Natural Language Processing task. sttClient.py -credentials : -model en-US_BroadbandModel -threads 10 Options ![]() The example below performs the same task much faster by opening 10 simultaneous recognition sessions (WebSocket connections) against the STT service. sttClient.py -credentials : -model en-US_BroadbandModel The example below will run the default 10 WAV files through the WebSockets interface of the Speech To Text (STT) service and will dump the recognition hypotheses to a file under the "./output" directory. If you are creating an environment using anaconda, proceed with the above pip command to install the packages-do not use conda to install the requirements as conda will install nose as a dependency. $ apt-get install build-essential python-dev In order to interact with the STT service via WebSockets, it is necessary to install pip, then write the following commands: Certain packages have been observed to conflict with the package requirements for this script in particular the package nose conflicts with these required packages. The WebSocket interface of the IBM Watson Speech to Text service is the most natural way for a client to interact with the service. ![]() It is advisable to install the required packages in a separate virtual environment. There are some dependencies that need to be installed for this script to work. It can run N simultaneous recognition sessions Installation For example, you can use it to develop analytics for a call-center or meeting transcript, or to animate an exchange with. You can use the feature to create a person-by-person transcript of an audio stream. The client streams audio to the STT service and receives recognition hypotheses in real time. With speaker labels, the IBM Watson Speech to Text service identifies which individuals spoke which words in a multi-participant exchange. This project consists of a python client that interacts with the IBM Watson Speech To Text service through its WebSockets interface. Please use the Official Watson Python SDK Synopsis Specify a value of -1 to set the inactivity timeout to infinity.This sample has been deprecated. You can override this timeout by specifying a different value for the inactivity_timeout parameter. The timeout is useful, for example, for terminating a session when a user simply walks away from a live microphone. The service uses the inactivity timeout to ensure that a session remains active. Your application should also recover gracefully from closed connections.Īn inactivity timeout (HTTP status code 400) occurs when the service is receiving audio from the client but it detects silence (no speech) for 30 seconds. Ideally, you would establish a session just before you obtain audio for transcription and maintain it by sending audio at a rate that is close to real time. (You must also set the inactivity_timeout parameter to -1, as described in the next bullet.) You are charged for the duration of any data that you send to the service, including the silence that you send to extend a session. If the client has sent all data, the service can take more than 30 seconds to generate a response in this case, the request does not time out.įor both WebSocket connections and HTTP sessions, you can keep a session active by sending any audio data, including just silence, before the 30-second session timeout occurs. The latter condition occurs only if the service receives no data from the client for 30 seconds and it has not yet received the last chunk of data. It also occurs when a session is active but no request is received from the client for 30 seconds. If one of these timeouts lapses, the service closes the connection.Ī session timeout (HTTP status code 408) occurs when a client starts a session but the service receives no audio for 30 seconds. To preserve resources when you stream audio data, the service enforces various timeouts. This is probably a timeout from the Speech to Text service: ![]() Hi Is there any more information you could provide? ![]()
