README

b'TextToSpeech (TTS) is a text to speech service TANGO device server. It is based on Amazon Web Services (AWS), and writes its audio via Pulse Audio. The device server currently includes some simple file caching services, to reduce the interaction with AWS.\n\nThe main text to speech and audio playback code has been separated out into a static library that is linked to both the device server and the unit tests. This separation allows the TTS functionality to be tested per class, and TTS code developed in isolation to the device server. It also reduces the dependencies of the unit tests.\n'
