Speech recognition and synthesis are two distinct but related technologies that deal with processing and generating human speech. Speech Recognition, or Automatic Speech Recognition (ASR), is the technology that converts spoken language into text, whereas Speech Synthesis, or Text-to-Speech (TTS), is the technology that converts text into spoken language.

Speech recognition is a technology that converts spoken language into written text. In Speech Recognition, speech is first captured as audio. Then, the software analyzes the sound waves, breaks them down into phonemes (basic sound units), and compares them to known language models to recognize words and their meaning.

There are different approaches and technologies used for speech synthesis, including rule-based systems, concatenative synthesis, and more recently, deep learning techniques such as neural text-to-speech (NTTS). In Speech Synthesis, text is analyzed and broken down into phonemes. The TTS software then selects appropriate sounds from its database and combines them to produce speech output.
