Android's Text To Speech (TTS) System

The voice output for Appicenter's langues apps make use of Android's Text To Speech (TTS) engine infrastructure. Often TTS engines are pre-installed but they can also be installed from the Google Playstore. Engines can be selected and activated under menu [Settings] :: [Language&Input] :: [Text-to-speech output] or similar.
Typically voice sets for each desired output language need to be installed as well.

Older Android phones do not come with any TTS engine and newer android phones often lack a proper Portuguese voice set resulting in either no or very robotic sounding voice output. The default TTS engine installed on Samsung phones often causes problems and we recommend switching to the standard Google one instead.

The standard Google TTS engine is used on many phones and tablets and in our experience your best choice. It can be downloaded for the Play Store by following this link. Note that the engine behaves differently depending on whether the device is on-line or off-line. For off-line use you may need to download additional voice sets.

After installing the new engine do not forget to activate and configure it in the menu mentioned above.

If the >standard Google TTS engine does not work for you several third party TTS engines are available in the Google Play Store to fill the gap. Below is commented list:

SVOX Pico

The standard TTS engine for older Android versions - does not work with newer Android versions. The voices are of medium quality but a Portuguese voice set is not included.

SVOX Classic

The updated version of the SVOX TTS engine. It has a lot of different voice sets available for purchase. Unfortunately, it does not handle the coexistence of multiple voice sets, e.g. English and Portuguese, very well so this engine is no longer recommended by us.

IVONA Text-to-Speech

Very nice engine with high quality voice sets. Currently free but voice sets are very large and no Portuguese voice set is available.

Acapela TTS

Engine with good quality voice sets including Portuguese.
