Explanation

Speech recognition involves converting spoken words to data. It transforms audio recordings or live microphone input into a format that computers can understand, often by converting them to text (transcription). The process of analysis has two components:

  • Acoustic model: Analyzes the audio to identify patterns and map them to phonemes (basic units of sound).
  • Language model: Uses statistical methods to predict the most likely sequence of words based on the identified phonemes and knowledge of language patterns.

Speech recognition applications include:

  • Closed captions for videos
  • Transcription of phone calls or meetings
  • Automated note dictation
  • Determining user input for further processing

Speech synthesis involves vocalizing data and converting text into spoken audio output. Its required information includes:

  • Text to be spoken
  • Voice selection (e.g., male, female, accent)

The process of speech synthesis has the following components:

  1. Tokenization: Breaking down text into individual words.
  2. Phonetic assignment: Assigning phonetic sounds to each word.
  3. Prosodic unit creation: Grouping words into phrases, clauses, or sentences for proper intonation.
  4. Phoneme conversion and audio generation: Converting phonemes to audio with a chosen voice, speaking rate, pitch, and volume.

Speech synthesis applications include:

  • Spoken responses to user input (e.g., virtual assistants)
  • Voice menus for phone systems
  • Reading text messages or emails hands-free
  • Public announcements in various locations
