Speech
The concept of speech technology encompasses two technologies: synthesizers and recognizers. A speech synthesizer takes text as input and produces an audio stream as output. Speech synthesis is also referred to as text-to-speech (TTS). A speech recognizer, on the other hand, does the opposite. It takes an audio stream as input, and turns it into a text transcription.
