Audio Typo 13

Something different today: instead of changing code of a font-file, I started working with TTS-programs.

Text to Speech programs use images or text as input and produce spoken words and sentences.

In the example below you can see the text of a song set in OCR-A (Optical Character Recognition). Back in the early days of computing, there was a need to create a standardized font that could be read by both computers and humans. The result of this was the OCR-A font. To test the limits of readability of this font I increased the stroke thickness of every paragraph until unreadable. Next, I processed this through Prizmo to hear what sound it produces.

In the first paragraphs, there’s not really a problem but after a while the text is being read as an image, and doesn’t produce sound. What’s funny is the recognition of some letters at one of the last paragraphs (paragraph 13).
