About NCH Speech Synthesizer Engines

A collection of speech synthesizer and recognition engine technologies used within NCH Software applications.

NCH Speech Synthesizer Engines is not a standalone product but a set of text-to-speech and speech recognition technologies integrated into various NCH Software applications like Verbose Text to Speech and WavePad Sound Editor. These engines use the computer's default SAPI 4 or SAPI 5 compliant voices (like Microsoft Sam or Anna) but also support the installation of third-party voices for higher quality audio. The technology enables core functions such as converting written text to spoken words, allowing hands-free voice commands for software control, and performing keyword searches within audio recordings by converting speech to text. This functionality is aimed at users needing accessibility features or enhanced productivity within the NCH software ecosystem. No specific pricing is available as it is a feature of other products.

  • Integrates text-to-speech and voice command features into multiple NCH software products.

Cons
  • This is not a standalone, purchasable product, but a feature set within other applications.
  • Effectiveness depends on the quality of the underlying SAPI voice engine installed on the user's computer.
  • SAPI 4 is not supported on modern Windows versions like Vista, 7, and later.
