Voice.ai
Voice.ai provides real-time AI voice transformation for PC, alongside text-to-speech and online audio tools. Its PC app describes its voice engine as deep-learning based and lets users hear a changed voice in real time. A library of user-generated voices and voice cloning are also listed. Voice.ai says transformed speech is returned in the speaker’s language. On Windows, it can work with microphone-enabled apps such as Discord, Zoom, Google Meet, WhatsApp, Skype and Twitch, plus games including Minecraft and Fortnite. The platform listing includes Windows, Mac, iOS and Android, while its API offering covers voice agents, cloning and text-to-speech. The free plan includes 5k credits/month and a five-minute audio conversion limit. Starter costs $5 a month and includes 15k credits/month and five instant voice clones. Higher plans add credits, clones, concurrent generation and agent-call capacity, with priority support on Core and technical success manager support on Business.
