Speech Recognition In computer science, speech recognition (SR) is the translation ofspoken words into text .

Also known as:

automatic speech recognition (ASR) computer speech recognition speech to text

Some SR systems use training where an individual speaker readssections of text into the SR system. These systems analyse theperson's specific voice and use it to fine tune the recognition ofthat person's speech, resulting in more accurate transcription.

Speech recognition applications include:

- voice user interfaces such as voice dialling ( e.g. Call home )- call routing ( e.g. Id like to make a collect call from England to )- domestic appliance control ( e.g. windows, lightning, etc. )- Internet search ( e.g. find a podcast where particular words were

spoken )- simple data entry ( e.g., entering a credit card number )

- speech-to-text processing ( e.g., word processors or e-mails )

Voice recognitionThe term voice recognition refers to finding the identity ofwho is speaking, rather than what they are saying.

Recognising the speaker can simplify the task of translatingspeech in systems that have been trained on specificperson's voices or it can be used to authenticate or verifythe identity of a speaker as part of a security process .

Forensic Phonetics Area of phonetics that deals with questions in which speaker identification is relevant tosolving a crime.

Prominent cases: hoax calls to emergency numbers (e.g. 999) sexual harassment calls

bank robberies in which robbers are maskedbut recorded telephone calls from kidnappers crimes (e.g. rapes) in darkness in which

victim cannot see but hear the perpetrator.4


6/8

To a high degree we can identify speakers solely on thebasis of their voice. (e.g. in telephone calls)

- Every speaker has individual features in the acousticsignal of his/her voice. ( consonantal sounds, vocalicsounds, pitch, intonation accent/dialect, socialbackground, age, mood ).
