Speech synthesis of food data

[LuccoJ]

The application could be used as an accessibility aid for people who can't easily read the (usually very small) ingredient lists or other data on food labels.
This possibility would be enabled, or at least improved, if the app had support for speaking out ingredients and other data after scanning a barcode, using Android's TTS API in the appropriate language.

The current implementation is an ON/OFF toggle.

• Can it be autodetected ?
• Keeping the On/Off toggles lets contributors make a case for the usefulness of Open Food Facts for people with vision disabilities.

[LuccoJ]

Please keep the toggle, because speech synthesis can be useful even for people without severe enough vision disabilities to have other aids enabled on Android (which I assume you would use to autodetect). Ingredient lists and nutritional tables are often just very tiny. Of course, the toggle in addition to autodetection would be fine.

@teolemon for Android's TTS API we need the locale of the string that needs to be spoken out. Currently, we do not know the ingredient's language. We just display what we get in the JSON from the server without any knowledge of the locale of this string. Therefore to implement this feature we need to update the API to get information about the Ingredient's language.
