  in computer science and electrical engineering, speech recognition (sr) is the translation of spoken words into text. it is also known as "automatic speech recognition" (asr), "computer speech recognition", or just "speech to text" (stt). some sr systems use "speaker-independent speech recognition" while others use "training" where an individual speaker reads sections of text into the sr system. these systems analyze the person's specific voice and use it to fine-tune the recognition of that person's speech, resulting in more accurate transcription. systems that do not use training are called "speaker-independent" systems. systems that use training are called "speaker-dependent" systems. speech recognition applications include voice user interfaces such as voice dialling (e.g. "call home"), call routing (e.g. "i would like to make a collect call"), domotic appliance control, search (e.g. find a podcast where particular words were spoken), simple data entry (e.g., entering a credit card number), preparation of structured documents (e.g. a radiology report), speech-to-text processing (e.g., word processors or emails), and aircraft (usually termed direct voice input). the term voice recognition or speaker identification{{cite web|title=speaker identification (whisperid)|url=http://research.microsoft.com/en-us/projects/whisperid/|work=microsoft research|publisher=microsoft|accessd
