Made a couple of changes to how the wave-form is displayed. AN ESP32 using pin 26 to read the output from the MOVI speech synthesizer, and output a display for the TV. Harvard Sentences: https://www.cs.columbia.edu/~hgs/audio/harvard.html The Harvard sentences are a collection of 720 sample phrases, divided into lists of 10, used for standardized testing of VoIP, cellular, and telephone systems. They are phonetically balanced sentences that use specific phonemes at the same frequency they appear in English. https://en.wikipedia.org/wiki/Harvard_sentences (NOW used for testing of the speech synthesizer as well 😃 ) Tue, 20 Oct 2026 14:13:02 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://diode.zone https://diode.zone/lazy-static/avatars/61b689b7-84d5-43c7-9fa8-e63a7fd1d952.png https://diode.zone/videos/watch/420626e0-b866-406c-80cc-aa6f06a66d10 All rights reserved, unless otherwise specified in the terms specified at https://diode.zone/about and potential licenses granted by each content's rightholder.
