Summary Nested classesĬonstants and parameter names for controlling text-to-speech. When you are done using the TextToSpeech instance, call the shutdown() method to release the native resources used by the TextToSpeech engine. Implement the TextToSpeech.OnInitListener to be notified of the completion of the initialization. The list of supported languages is going up - v3.0 adds support for Portuguese (Brazil) and Spanish (US).Synthesizes speech from text for immediate playback or to create a sound file.Ī TextToSpeech instance can only be used to synthesize text once it has completed its initialization. New languages: Portuguese and Spanish (United States) English (UK) male voiceĭid you notice in the screenshot above that English UK is no longer limited to the default female voice? You can now select regular or high-quality variants of both female and male voices. Oh, and for whatever reason, Google Maps ignores the TTS settings altogether, it seems. Google has a lot of room for optimizations here, that's for sure. However, something like "what is my next appointment" does use the new voices, with one pretty big caveat - as it turns out, loading such large voice packs could take up to 10 seconds even on a Nexus 5, which means the voice output could be severely delayed the first time you run Search after a reboot. I had male English UK selected, but the result came back in female English UK. Responses vary based on the questions asked - for example, "what is 3+2" seems to be streaming speech from the server, and while it does honor the language you choose in Search's settings, it doesn't use local TTS at all. Update: I have tested the new high-quality languages in Google Search, and the results are mixed.
