Recognize Audio Clips

Note: Before IDOL Speech Server can recognize audio clips, you must train the Speech Server. For information about training IDOL Speech Server, refer to the IDOL Speech Server Administration Guide.

To recognize audio clips

  1. Create a new configuration or open an existing configuration to send to Media Server with the process action. Alternatively, you can modify the Media Server configuration file (mediaserver.cfg).

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

    [Analysis]
    AnalysisEngine0=AudioMatch
  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 AudioMatch.
    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.
    Pack The name of the audio fingerprint database to use for recognizing audio clips. You must train Speech Server before configuring Media Server.
    AudioMatchServers

    The host name and ACI port of the Speech Server(s) to use for audio matching. Separate the host name and port with a colon (for example, speech:15000). You can specify multiple IDOL Speech Servers by using a comma-separated list. Media Server can connect to only one IDOL Speech Server at a time, but you can provide multiple servers for failover.

    Tip: You can specify a default IDOL Speech Server to use for all audio match tasks by setting the AudioMatchServers parameter in the [Resources] section of the Media Server configuration file.

    SampleFrequency (Optional) The sample frequency of the audio to send to the IDOL Speech Server for analysis, in samples per second (Hz).

    For example:

    [AudioMatch]
    Type=AudioMatch
    Pack=Music
    AudioMatchServers=speech:15000
    SampleFrequency=16000

    For more information about the parameters that you can use to configure audio matching, refer to the Media Server Reference.

  4. Save and close the configuration file. If you modified the Media Server configuration file, you must restart Media Server for your changes to take effect.
