Contains data required by engines to synthesize speech. This data is:

• The text to synthesize
• The synthesis locale, represented as a language, country and a variant. The language is an ISO 639-3 letter language code, and the country is an ISO 3166 alpha 3 code. The variant is not specified.
• The name of the voice requested for this synthesis. May be empty if the client uses TextToSpeech.SetLanguage(Java.Util.Locale) instead of TextToSpeech.SetVoice(Voice)
• The synthesis speech rate, with 100 being the normal, and higher values representing higher speech rates.
• The voice pitch, with 100 being the default pitch.

Any additional parameters sent to the text to speech service are passed in uninterpreted, see the params argument in TextToSpeech.Speak(Java.Lang.ICharSequence, Android.Speech.Tts.QueueMode, Android.Speech.Tts.QueueMode, Android.Speech.Tts.QueueMode) and TextToSpeech.SynthesizeToFile(Java.Lang.ICharSequence, Android.OS.Bundle, Android.OS.Bundle, Android.OS.Bundle).
