What they are
HeyGen
HeyGen generates studio-quality videos using AI avatars and text-to-speech voices, so creators and marketers can produce talking-head content without filming themselves. It supports over 175 languages and lets you clone your own voice and likeness. Teams use it for product explainers, onboarding videos, and localized content at scale. The avatar quality is impressive for scripted material, but unscripted or conversational styles still feel noticeably synthetic.
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.
