What they are
Speechify
Speechify converts text from PDFs, articles, emails, Google Docs, and ebooks into spoken audio using AI-generated voices. It is used by students, professionals, and people with dyslexia or reading difficulties who want to consume written content faster or more comfortably. The voice quality is genuinely good at normal speeds, but at very high playback rates naturalness degrades noticeably. The free tier is limited to one standard voice and a capped speed.
Synthesia
Synthesia generates studio-quality videos using AI avatars that lip-sync to a typed script, with no camera, microphone, or editing software required. It targets corporate trainers, marketers, and course creators who need to produce multilingual video content at scale. The output looks polished but has a recognizable AI avatar aesthetic that some audiences find less engaging than real presenters. Pricing starts at $14 per month on the Starter plan.
