Speech recognition AI, also known as automatic speech recognition (ASR), is a technology that enables computers and applications to understand and transcribe human speech into text format. The following overview will provide an understanding of the underlying principles of this technology.

How Speech Recognition AI Works

  1. Audio Capture: The speech recognition system initiates the process by capturing the audio input from a microphone or other audio source.
  2. Signal Processing: The audio signal is subjected to a series of processing operations with the objective of removing noise and enhancing the speech components.
  3. Feature Extraction: The audio signal is subjected to a process of feature extraction, during which relevant features, such as frequency, energy, and pitch, are isolated and converted into a sequence of feature vectors.
  4. Acoustic Modeling: The feature vectors are subjected to a comparison process against pre-trained acoustic models, which map the audio features to phonetic representations (e.g., vowels, consonants).
  5. Pronunciation Modeling: Subsequently, the phonetic representations are mapped to word candidates via the use of a pronunciation dictionary.
  6. Language Modeling: The term “candidates” is analyzed in the context of the language’s grammar, syntax, and semantics in order to determine the most probable word sequence.
  7. Output: The recognized word sequence is then outputted as text or utilized for further processing, such as executing a command or generating a response.

Key Components and Techniques

  • Acoustic Models: Statistical models have been trained on large speech datasets with the objective of mapping audio features to phonetic units.
  • Language Models: Statistical models have been trained on text data in order to predict the likelihood of word sequences based on grammatical and contextual factors.
  • Deep Learning: Neural networks, particularly recurrent neural networks (RNNs) and transformers, are frequently employed for acoustic and language modeling, demonstrating superior performance compared to traditional statistical methods.
  • Speaker Adaptation: The objective of this study is to develop techniques to adapt speech recognition models to individual speakers or accents in order to improve the accuracy of the models.
  • Noise Robustness: This section will present methods for handling background noise and other environmental factors that can degrade recognition accuracy.

Speech recognition AI has a multitude of applications, including virtual assistants, dictation software, call center transcription, and accessibility tools for individuals with disabilities.
