Text-to-speech (TTS) is a form of speech synthesis that converts text into spoken words. Text-to-speech is an easy way to add a dynamic voice to your phone capabilities. Unlike pre-recorded audio, this feature can be used to deliver spoken versions of text; live information (e.g., sports scores), emergency updates, and other dynamic messages. Simple changes in the code can allow you to change the message, the gender of the voice, determine who will receive your message, and much more.
