Module 10: Advanced & Security

Lesson 108: espeak Command

In this lesson, you’ll learn to use the espeak command to convert text into speech, customize voice settings, and apply it in scripts for alerts and automation.

The espeak command is an open-source text-to-speech (TTS) synthesis engine that uses a formant synthesis method. It generates speech by mathematically modeling the human vocal tract rather than stitching together recorded audio samples.

This makes espeak extremely lightweight (the entire engine and all language voices fit in a few megabytes), fast to respond, and capable of speaking in over 100 languages and dialects.

The trade-off is that it sounds more robotic than neural TTS engines like Google's or Amazon's, but for command-line scripting, system alerts, and accessibility use cases, that is often perfectly acceptable.

1. Speak a Simple Text String

espeak "I Love TecMint.com"

espeak immediately speaks the text through your system's default audio output — no additional configuration needed if your audio is working.

The speech is synchronous by default — the command does not return to the shell prompt until it has finished speaking.

💡
Note: If you hear no audio, check that your system volume is not muted and that espeak has access to the audio device. On headless servers without audio hardware, espeak it will fail silently and use-w a WAV file instead.

2. List All Available Voices and Languages
