Phonemes In Spoken Language

The processing of recognizing and responding to the meaning embedded in spoken words is defined as speech recognition. Phonemes are series of corresponding sounds part of each letter of the alphabet. When a computer recieves input from speech recognition, it has to break down a word into the different phonemes to determine what word was being said. Likewise, if a whole sentence or phrase was said, the computer has to work to find the different starting and ending points of each phoneme, while also recognizing points of silence to indicate different words. Sound is captured in analog form and is then transformed into digital form by method of digital sampling, and the resulting digital pattern is compared with a library of patterns corresponding to known phonemes. There are
These are most commonly found in anything that has automation involved with it, like calling a doctor's office for an appointment or recieving bank information. Audio response units act as an information system's output device. Words or phrases are digitally stored and recorded. To output a message, the stored message is retrieved and sent to a device that converts the digitalized voice into analog audio signals, which can then be speaker output. All possible outputs must be recorded in advance. Sentences can be generated from stored words, however the sentences sound choppy and unnatural because the transitions and breaks in between words is generated by the computer rather than an actual person. Speech synthesis is when the phonemes are stored within the system, so the computer can relay back a more clear message. Character outputs are sent to a processor which assembles corresponding groups of phonemes to generate synthetic speech. Creating natural sounding speech generation requires sophisticated processing. However the computer can handle speech generation a lot smoother than it can handle speech
