How do they work?

Text-to-speech

Text-to-speech (TTS) converts text into spoken words. It’s sometimes also referred to as “read aloud” technology.

It is useful providing callers with consistent voice messages, automating speech, and personalizing responses.

  • Text analysis: The technology first analyzes the inputted text – e.g. inputs form a caller during an IVR process
  • Phonetics: It will then determine the rhythm, pitch etc. of its response to help form human-like speech
  • Synthesis: The speech’s waveform is generated using snippets of real human speech combined with synthesis
  • Output: A real-time stream of speech is generated and played (generation of a .wav audio file is also an option)

Speech-to-text

Speech-to-text (STT) converts spoken language into written text. It’s sometimes also called automatic speech recognition (ASR).

It provides several benefits including automatic call transcription, help with quality monitoring and training, and documenting all calls in full.

  • Audio input: The call’s spoken words are captured via telephone and are processed to improve its analysis
  • Analysis: The call’s audio is broken down (feature extraction) so that it can be used for speech recognition
  • Modeling: The technology conducts acoustic and language modeling to improve the eventual generated text
  • Output: The raw outputted text is processed for errors and corrected before transcribing into the the final text
