Speech recognition is an interdisciplinary subfield of computer science and computational linguistics that develops methodologies and technologies that enable the recognition and translation of spoken language into text by computers. It is also known as automatic speech recognition ( ASR ), computer speech recognition or speech-to-text ( STT ).
Speech recognition is at an early stage of development. Specialized devices can recognize few words and accuracy is not very high. [1] 1971–1987. Speech recognition rapidly improves, although the technology is still not commercially available. [1] 1987–2014. Speech recognition continues to improve, becomes widely available commercially, and ...
Speech Recognition & Synthesis. Speech Recognition & Synthesis, formerly known as Speech Services, [ 2 ] is a screen reader application developed by Google for its Android operating system. It powers applications to read aloud (speak) the text on the screen, with support for many languages. Text-to-Speech may be used by apps such as Google Play ...
Voice computing is the discipline that develops hardware or software to process voice inputs. [1] It spans many other fields including human-computer interaction, conversational computing, linguistics, natural language processing, automatic speech recognition, speech synthesis, audio engineering, digital signal processing, cloud computing, data ...
Voice activity detection. Voice activity detection ( VAD ), also known as speech activity detection or speech detection, is the detection of the presence or absence of human speech, used in speech processing. [1] The main uses of VAD are in speaker diarization, speech coding and speech recognition. [2] It can facilitate speech processing, and ...

Each speaker recognition system has two phases: enrollment and verification. During enrollment, the speaker's voice is recorded and typically a number of features are extracted to form a voice print, template, or model. In the verification phase, a speech sample or "utterance" is compared against a previously created voice print.
Voice analysis is the study of speech sounds for purposes other than linguistic content, such as in speech recognition. Such studies include mostly medical analysis of the voice ( phoniatrics ), but also speaker identification. [1] More controversially, some believe that the truthfulness or emotional state of speakers can be determined using ...
