Need to turn text into spoken audio? AI text-to-speech has come a long way — voices now sound natural and expressive, not robotic. And with ToolLab's BYOK model, you can use your own OpenAI key for premium voices at cost.

BYOK — You Control the Cost
ToolLab uses your OpenAI API key for TTS. OpenAI charges $0.015 per 1,000 characters — that means a full article costs about 5-10 cents to convert. You get premium quality at cost, and we never see your key or your content.
