synthesizes the contents of expr as an Audio object.


uses the specified voice to synthesize the speech signal.

Details and Options

  • Speech synthesis is also known as text to speech and attempts to produce naturally worded speech rather than literal representations of expression structure.
  • SpeechSynthesize["string"] synthesizes the text in "string".
  • SpeechSynthesize[expr] works with mathematical expressions, graphics and other constructs.
  • SpokenString[expr] gives the text of the speech generated by SpeechSynthesize[expr].
  • SpeechSynthesize[expr] synthesizes using a default voice. $VoiceStyles lists all available voices.
  • SpeechSynthesize accepts all SpokenString options with the following additions:
  • Language"English"the language to use for synthesis
    MethodAutomaticmethod settings to use
    OverwriteTargetFalsewhether to overwrite an existing file
  • By default, the synthesized speech is placed under the "Audio" directory in $WolframDocumentsDirectory.
  • Use Method->{"StorageLocation"->loc} to specify the location of the generated signal. Possible settings for loc include:
  • Automatican audio object linking to a file with automatically generated name
    filean audio object linking to file
    "Memory"an in-memory audio object
  • Using Language->Automatic, the language of "string" is identified using LanguageIdentify.
  • SpeechSynthesize uses machine learning. Its methods, training sets and biases included therein may change and yield varied results in different versions of the Wolfram Language.
