How can speech recognition be improved?
One of the most important factors for improving voice recognition is to use a high-quality headset microphone that holds the microphone in a consistent position directly in front of your mouth; desktop-based microphones typically provide less desirable voice-recognition results because they don't remain consistently ...
What is speech recognition performance?
Performance. The performance of speech recognition systems is usually evaluated in terms of accuracy and speed. Accuracy is usually rated with word error rate (WER), whereas speed is measured with the real time factor. Other measures of accuracy include Single Word Error Rate (SWER) and Command Success Rate (CSR).
What are the techniques for speech recognition?
Speech recognition involves three processes: extraction of acoustic indices from the speech signal, estimation of the probability that the observed index string was caused by a hypothesized utterance segment, and determination of the recognized utterance via a search among hypothesized alternatives.
Which are the key features for effective speech recognition?
Key features of effective speech recognition
They integrate grammar, syntax, structure, and composition of audio and voice signals to understand and process human speech. Ideally, they learn as they go — evolving responses with each interaction.
