Emotion plus a rate that works at any scale

Hume Octave sells in subscription tiers from $3 a month to $500 a month, with the effective rate landing around $50 to $150 per million characters depending on the tier; for a small project the subscription floor is the bill, and for a big project the high tier is the bill. SpeechifyAI is from $6 per million characters across every plan, with no subscription floor on the lowest paid tiers, so the bill scales with the work rather than with the plan size picked at signup.

The verdict

SpeechifyAI is from $6 per million characters across every plan with no subscription floor, professional voice cloning included on Starter and above, a 1,500+ voice catalog covering 30+ languages, and a 99.9% uptime SLA in the contract.
