About Chant Audio Search

Find the time offsets for specific words, phrases and subphrases in audio recordings.

Chant Audio Search enables applications to find the time offsets for specific words, phrases and subphrases in audio recordings. The search terms can be a simple string or Regular Expression pattern. Class libraries are available for C++, C++Builder, Delphi, Java, C#, and VB.NET Windows applications.

Audio Search Features

  • The search terms can be a simple string or Regular Expression pattern.
  • An audio recording is transcribed first from which one or more searches may be performed. Matches are returned for the entire recording as offsets in seconds.
  • There are two types of audio searches supported transcription and word spotting:
    • With transcription searches, an audio recording is transcribed first. Then one or more searches may be performed with simple string or Regular Expression pattern search terms. Matches are returned as offsets in seconds.
    • With word spotting searches, the audio is word spotted with a list of keywords (i.e., single words or phrases) first. Then one or more searches may be performed to match a keyword originally used in the word spotting. Matches are returned as offsets in seconds.
  • Audio Search class libraries are available for C++, Embarcadero C++Builder, Embarcadero Delphi, Java, C#, and VB.NET Microsoft Windows applications.
  • Integration is simple and fast because a single line of code performs the search and returns offsets in the audio recording if found.
  • Chant Application Helpers provide ready-to-use capabilities for fast application integration. They are designed to yield specific results with minimal application coding requirements.
