Speechify
Speechify is the mainstream 'read anything aloud' assistant, claiming 55M+ users and topping the App Store's text-to-speech charts. The same engine is available as a developer TTS API (1,000+ voices, 60+ languages, instant voice cloning, SSML, streaming), so it spans consumers and builders. The free tier is deliberately thin -- 10 robotic voices, TTS-only -- and consumer Premium is $29/mo, while API pricing is signup-gated rather than public. Its edge is distribution and reach, not raw model novelty.
Udio
Udio is the strongest competitor to Suno for AI music generation, with noticeably higher audio fidelity and more nuanced musical arrangement, especially for jazz, classical, and emotionally complex pieces.
Speechify edges Udio on aggregate — 79 vs 71.
The mainstream consumer read-aloud assistant -- huge reach and a capable API -- but a stingy free tier and signup-gated API pricing are the catch. Udio still wins for buyers who prioritise higher audio fidelity than suno - noticeably better on acoustic instruments. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
