Media Server 24.1

# Transcribe Speech

To run speech-to-text

1. Create a new configuration to send to Media Server with the `process` action, or open an existing configuration that you want to modify.

2. In the `[Session]` section, add a new analysis task by setting the `EngineN` parameter. You can give the task any name, for example:

       [Session]
       Engine0=Ingest
       Engine1=TranscribeSpeech

3. Create a new section to contain the settings for the task and set the following parameters:

   `Type` | The analysis engine to use. Set this parameter to `SpeechToText`.
   `Input` | (Optional) The audio track to analyze. If you do not specify an input track, Media Server processes the first track of the correct type produced by the ingest engine.
   LanguagePack | The language pack to use. For a list of available language packs, see Speech Analysis Supported Languages. If your session configuration includes Language ID, you can instruct Media Server to use the detected language: set `Input` to the `ResultWithSource` track from your Language ID task. set `LanguagePack=input`. NOTE: `LanguagePack=Input` is not available when `ModelVersion=Legacy`.
   ModelVersion | The model to use to convert speech into text.
   SpeedBias | Specifies whether to prioritize accuracy or speed. If you are processing a live stream, you must set this parameter to `Live`. Otherwise, set this parameter to an integer from `1` to `6`, where `1` prioritizes accuracy and `6` prioritizes speed.

   For example:

       [TranscribeSpeech]
       Type=SpeechToText
       LanguagePack=ENUK
       ModelVersion=small
       SpeedBias=2

   For more information about the parameters that you can use to configure speech-to-text, see Speech-To-Text.

4. Save and close the configuration file. OpenText recommends that you save your configuration files in the location specified by the `ConfigDirectory` parameter.
