What Altered does
Altered is a London-based AI voice technology company founded in 2021 that builds proprietary Speech-to-Speech Voice Morphing and related voice AI capabilities into two core products: Altered Studio, a voice content creation platform for media production, and Real-Time Pro, a low-latency voice changer for live voice and video calls. The underlying technology stack combines traditional DSP audio effects with proprietary AI models for voice morphing, voice cloning (including Rapid Voice Cloning from 5–15 seconds of audio and Local Voice Cloning on user GPU), Text-to-Speech with 14 speaking styles across 70+ languages, transcription in 75+ languages, AI denoising and voice cleaning, cross-lingual Timbre models, and accent translation. The platform is offered across web (altered.studio), desktop (Windows and Mac), and mobile app stores, with an API and on-premise server options for enterprise clients.
The company serves multiple segments including content creators, video game developers, film and television studios, call centers, eLearning, and individuals with voice impairments (via the Euphonia voice restoration feature). Revenue is generated through tiered subscriptions (Creator, Professional, Enterprise, Educational, and Real-Time Pro plans including a discounted AI Improvement Program tier), four license types governing usage rights, and premium Custom Voice Services for high-end productions. Notable deployments include voicing 800 lines of dialogue for 40 NPC characters in the game 'The Ascent' and providing AI-generated voice clones for child actors in film/TV productions. The company publishes an Ethics Code, is GDPR/CCPA compliant, and positions itself as a responsible AI provider in a market where misuse risk is material.
