Summary
Modern AI text-to-speech systems for screen reader users have not significantly evolved in the past 30 years. The requirements for blind users differ greatly from those of sighted users, leading to a lack of advancements in the voices available for screen readers.
Key Takeaways
- The text to speech technology used by blind users has not significantly evolved in the last 30 years, with the preferred voice, Eloquence, last updated in 2003.
- Blind users prefer text to speech voices that are fast, clear, and efficient, often at speaking rates of 800 to 900 words per minute, contrasting with sighted users' preference for more natural-sounding voices.
- Modern AI-based text to speech systems like Supertonic and Kitten TTS are being explored for integration into screen readers, as they claim to be fast and responsive without requiring a GPU.
- The open-source text to speech system espeak-ng faces challenges, including outdated design decisions and limited active maintenance, impacting its effectiveness for blind users.
Community Sentiment
Positives
- Modern speech-to-text systems are impressively fast and sound great, making them easy to implement, which is crucial for accessibility improvements.
- The 'supertonic' model exemplifies the advancements in TTS technology, demonstrating that even small models can perform exceptionally well.
Concerns
- Despite advancements, current TTS systems struggle with accuracy, often skipping words and misreading numbers, which undermines their utility for users.
- There is a significant disconnect between expectations for AI in screen reading and the actual capabilities, leading to frustration among users.
- The lack of support for screen readers in modern Linux environments raises serious concerns about accessibility, limiting the effectiveness of new TTS technologies.
