Voice cloning is the process of creating a digital copy of a human voice using AI. The model learns the unique characteristics of your speech — tone, pitch, accent, and rhythm — from a short recording, then generates new speech in that voice from any text you type. Unlike classic text-to-speech, which uses stock voices, a voice clone sounds like a specific person: you.
Acoust's AI voice cloner analyzes a short sample of your speech and builds a neural voice model from it. When you type a script, the model synthesizes audio that matches your voice's identity while applying natural pronunciation, pacing, and emotion. The cleaner your input audio, the better the clone — see the recording tips below.

Voice cloning is legal when you clone your own voice or have explicit permission from the voice’s owner — which is exactly how Acoust is designed to be used. Because voice cloning technology can be misused for impersonation scams, Acoust requires user consent and is built for authorized, responsible voice creation.Acoust uses Gemini models to power voice cloning and synthesis. Your voice data is used only to provide the service and is not shared, sold, or made publicly available by Acoust.Your voice clone stays under your control and you can delete it at any time.

You can create and preview your AI voice clone free with Acoust. On paid plans, voice cloning consumes 2x the credits of standard AI voices — see our pricing page for details.
Voice cloning technology uses AI and machine learning to capture the characteristics of a person's voice. Initially, it requires a substantial sample of the target voice. This sample is then analyzed to understand various speech nuances, such as pitch, tone, and rhythm. The AI uses this data to generate a digital model capable of reproducing the unique aspects of the voice. Once created, this model can synthesize speech that sounds like the original speaker, even saying words or sentences the original speaker never recorded.
To record studio-grade audio, ensure a quiet environment and use high-quality microphones. Proper microphone placement relative to the sound source is crucial. Utilize a pop filter to minimize plosives. Employ acoustic treatment to control reverb and unwanted echoes. Choose the right recording software that meets your needs and invest in a good audio interface for clear sound conversion. Finally, perform regular equipment maintenance and software updates to maintain audio quality.
