Text-to-speech engines read text aloud, saving users from having to read it themselves. Google's TTS offering comes pre-installed on numerous Android devices, and like much of the software previously shipped as part of Android, it's now ready to spread its wings in the Play Store. Here it's available to far more users, as it can now be installed on devices that don't come with the software pre-installed (pictured below -left). In contrast, on the Nexus 5, Google TTS is apparently already installed and unremovable (pictured below - right).
Improving on existing TTS technology, Loquendo (a Nuance company) is showing the world that "even computers can show their feelings," with a huge array of TTS engines that are not only more advanced, but significantly more dynamic than existing alternatives.
The bad news is that only two of these engines are currently available for Android – Italian TTS Paola and American English TTS Susan. That being said, we can still hope that more of Loquendo's engines will be adapted for Android, and, in the meantime, Loquendo's website has amazing demos of all its TTS voices, both static and interactive.
A fresh version of Google Translate hit the Market today. Conversation mode (direct speech to speech translation) now works in 14 languages: Brazilian Portuguese, Czech, Dutch, French, German, Italian, Japanese, Korean, Mandarin Chinese, Polish, Russian and Turkish. Also new is a personal dictionary, the ability to correct voice input before having it translated, and pinch zoom support for getting a close up of the translated text (Chinese symbols can get surprisingly complicated).
