Add Speakers to a Database

To add a speaker to a speaker database, follow these steps.

To add a speaker

  1. Create a new speaker using the NewSpeaker action. Set the following parameters:

    database The name of the database to add the speaker to. The database must already exist.
    identifier (Optional) A unique identifier for the speaker (maximum 254 bytes). If you do not set this parameter, Media Server generates an identifier automatically.

    For example:

    curl http://localhost:14000/action=NewSpeaker
                                -F database=news
                                -F identifier=newsreader

    Media Server adds the speaker and returns the identifier.

  2. Add audio samples for the speaker using the AddSpeakerAudio action. Set the following parameters:

    database The name of the database that contains the speaker.
    identifier The identifier for the speaker, as returned by the NewSpeaker action.
    audiodata (Set this or audiopath, but not both). The audio data to add. Files must be uploaded as multipart/form-data. For more information about sending data to Media Server, see Send Data by Using a POST Method.
    audiopath (Set this or audiodata, but not both). A comma-separated list of paths to the audio files. The paths must be absolute or relative to the Media Server executable file.
    audiolabels (Optional) A comma-separated list of labels to identify the audio samples that you are adding (maximum 254 bytes for each label). Every audio sample added to the same speaker must have a unique label, so the number of labels must match the number of samples provided using either audiodata or audiopath. If you do not set this parameter, Media Server generates labels automatically.

    For example:

    curl http://localhost:14000/action=AddSpeakerAudio
                                -F database=news
                                -F identifier=newsreader
                                -F audiodata=@sample1.wav,sample2.wav
                                -F audiolabels=sample1,sample2
  3. Train Media Server to recognize the speaker by running the BuildSpeaker action. Set the following parameters:

    database The name of the database that contains the speaker.
    identifier The identifier for the speaker, as returned by the NewSpeaker action.

    For example:

    curl http://localhost:14000/action=BuildSpeaker
                                -F database=news
                                -F identifier=newsreader
