This week, as part of the design presentation preparation, I was responsible for the use case & requirements and the quantitative design requirements. In addition to group efforts, I worked on local testing of the audio narration system using my laptop. Specifically, I
- installed and configured espeak-ng, a text-to-speech synthesizer, using Homebrew on macOS.
- tested speech output by generating WAV audio files
- experimented with different voice settings to create a spooky theme voice for trivia
- created a test script to automate the process of converting trivia questions into speech output
Right now, my schedule is on schedule. I am waiting for the parts to come so that I can continue and integrate the text-to-speech into the Raspberry Pi and speaker.
In the upcoming week, I am planning to begin writing 100 trivia questions and research potential libraries for smoother voice modulation. Assuming I have all the parts, I plan to conduct initial narration tests on the actual hardware ensuring clarity and correct volume, and modify the test script.
