Exercises:

Localisation x 2

The chapter describes how to localize strings to be used for TTS using the resources directories. But, how about the other way round? How can we localize ASR? We have shown how to specify the locale for open ASR, but if our app used handcrafted grammars, we would need to have a grammar for each supported language.

Use the directories approach to save the urls of different speech grammars for different languages, so that once a language is selected by the user or automatically obtained from their device settings, the ASR is started using a particular handcrafted grammar.

Multimodality meets semantics

Improve the MultimodalFormFillLib to support the use of semantic tags in grammars, so that in the SendMessage app, for each contact in the contact list the recognition obtains their phone number and not their name, so that they can be phoned directly.
