Speech Recognition
Speech recognition, also known as automatic speech recognition (ASR) or speech-to-text (STT) conversion, is a technology that enables computers to recognize and transcribe spoken language into text. It involves developing algorithms and systems that can analyze audio input, identify spoken words and phrases, and convert them into written text.
Capabilities
Our AI Speech recognition begins with the processing of audio input, which may come from various sources such as microphones, telephones, or audio recordings. The audio signal is typically digitized and pre-processed to enhance its quality and reduce noise or interference. Techniques such as filtering, noise reduction, and signal normalization are commonly used for this purpose.
Our Speech Recognition Once the audio signal is pre-processed, speech recognition algorithms extract relevant features from the audio data to represent the speech signal. These features may include spectral characteristics, frequency content, and temporal patterns of the audio signal. Common techniques for feature extraction include Mel-frequency cepstral coefficients (MFCCs), linear predictive coding (LPC), and spectrogram analysis.
Our speech recognition, acoustic models are used to map the extracted audio features to phonemes or basic units of speech sounds. Acoustic models capture the statistical relationships between audio features and phonetic units, allowing the system to recognize spoken words based on their acoustic properties. Hidden Markov Models (HMMs) and deep neural networks (DNNs) are commonly used for acoustic modeling in modern speech recognition systems.
Our Speech Recognition Technology helps in Language modeling is the process of representing the structure and patterns of natural language, including words, phrases, and grammatical rules. Language models help speech recognition systems interpret spoken language by predicting the likelihood of word sequences given the context of the conversation. Techniques such as n-gram models, recurrent neural networks (RNNs), and transformer models are used for language modeling in speech recognition.
Our Speech Recognition technology helps in Once the audio features have been extracted and modeled, the speech recognition system performs decoding to identify the most likely sequence of words that correspond to the input speech signal. This involves selecting the word sequence with the highest probability according to the acoustic and language models. Algorithms such as dynamic programming, beam search, and connectionist temporal classification (CTC) are commonly used for decoding and recognition.
