Speech enhancement is the process of improving the quality, clarity, and intelligibility of recorded or live speech. Typically this includes removing unwanted background noise, reducing reverberation, correcting distortions, and restoring lost audio details so that the voice sounds natural and easy to understand. Speech enhancement is widely used in telecommunications, broadcasting, media production, assistive listening devices, and in AI-powered applications in the Voice AI space.
A classic example is someone speaking in a noisy café. Speech enhancement would remove background chatter, the sound of footsteps and dishes, low-frequency hums and more, while also preserving the speaker’s natural voice and identity.
Depending upon the form of speech enhancement tool, this could be done either post-recording or live with real-time enhancement. For a post-recording use case, the recording might be used as an interview for broadcast. For a real time use case, the recording might be enhanced to improve the performance and success of a voice agent.
Speech enhancement combines signal processing techniques and artificial intelligence to isolate the human voice from unwanted sounds. Traditional methods rely on algorithms such as spectral subtraction or adaptive filtering, while modern AI-driven approaches use deep learning models trained on thousands of hours of speech and noise data. These models intelligently detect and suppress background noise, correct frequency imbalances, and reconstruct missing details in the voice signal.
Speech enhancement is at the heart of our AI-powered technology. Our proprietary AI models, Lark, Finch, and Quail, offer different use cases to provide the best in speech enhancement. For example, Quail prioritizes real time enhancement, while Finch is our leading speech isolation tool and Lark goes beyond typical speech enhancement to repair and restore lost frequencies.
Whether processing recordings in bulk or enhancing speech in real time on devices, our solutions remove noise, correct imperfections, and restore natural vocal warmth. This technology empowers developers, creators, and businesses to produce, process, and automate studio-quality sound without the need for expensive recording environments.
