About:
eSpeak is an open-source speech synthesizer that converts text into spoken audio. It supports a wide range of languages and dialects and uses a formant-based method to generate speech. This makes it highly resource-efficient and suitable for embedded systems and accessibility applications.
Key Features:
  • Supports multiple languages and dialects
  • Compact and resource-efficient design
  • Highly configurable speech parameters
  • Can output to various audio devices or files
Use Cases:
  • Providing screen reader functionality for visually impaired users
  • Generating audio feedback for embedded systems or robotics
  • Creating automated voice announcements for software applications
Alternatives:
  • festival – Festival offers high-quality synthesis but is generally larger and more complex to configure than eSpeak.
  • flite – Flite is a lightweight alternative similar to eSpeak but with a smaller set of built-in voices and languages.
