The text-to-speech voices used in Android applications are going to receive an upgrade to make them seem more natural and increase the clarity of the text-to-speech engine that Google uses for its Speech Services.
You can compare the new voices to the old sounds for yourself by listening to the taped excerpts that are available on the Android Developers Blog.
To tell you the truth, even if I can hear the voices more clearly, I don’t believe the claims that it sounds more realistic. It is also impossible to determine what the initial line in these US recordings that are in English actually says;
does it say that this is my gun? Is this the god I worship? According to what I’ve read, it asks, “Is this mic on?,” but I didn’t understand what that meant.
A new voice model and synthesizer will be applied to each of the system’s 421 voices, which are available in 67 different languages.
The default voice that is now used for “English-US” is going to be updated to one that was constructed using “fresher speaker data,” which, when combined with other improvements, will result in a discernible improvement over the previous default voice. You may also hear how the voices have been updated in languages like “Spanish-US” and “Brazilian-Portuguese.”
According to the update announcement, users who are already utilizing text-to-speech technology do not need to take any action in order to receive the new voices because “everything will happen behind the scenes” and the updates will be downloaded automatically.
This means that users do not need to take any action in order to receive the new voices. If you use an Android device, there is a good chance that you have already used the Speech Services by Google speech engine, even if you are unaware of it.
The listing for it on the Google Play Store states that the service is already used by a variety of native applications, such as Google Maps, Google Translate, and the Android Recorder app. All 64-bit Android devices will be able to access the update through the Google Play Store over the following few weeks once it has been released.
