eSpeak-NG Speech Engine

This test times how long it takes the eSpeak speech synthesizer to read Project Gutenberg's The Outline of Science and output to a WAV file. This test profile is now tracking the eSpeak-NG version of eSpeak.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark espeak.
