Text-to-Speech (TTS) is a form of speech synthesis that converts text into spoken voice output. TTS systems were first developed to aid the visually impaired by offering a computer-generated spoken voice that would ‘read’ text to the user. TTS is now common-place in virtual assistants such as Amazon Alexa and Apple's Siri. Amazon Polly converts input text into life-like speech. With Amazon Polly you call one of the speech synthesis methods, provide the text that you want to synthesize, choose one of the Neural Text-to-Speech (NTTS) or Standard Text-to-Speech (TTS) voices, and specify an audio output format. Amazon Polly then synthesizes the provided text into a high-quality speech audio stream.
