## Altered

Altered builds speech technology that separates the identity of a voice from the performance behind it. The platform is split into two clearly different products. Altered Studio is aimed at media production: it lets editors morph a recorded performance into any voice in a curated portfolio or a custom voice, clone a speaker from a short sample, generate natural text-to-speech narration and clean up noisy dialogue. Because it works after recording, it can use high-end GPUs and prioritise fidelity over speed. Altered Real-Time Pro is the live counterpart, using only a few CPU cores to transform a voice within milliseconds of it being spoken, which makes it usable in voice calls, streaming and games.

The real-time product is organised around job-specific feature sets rather than a single generic slider. Voice Skins let gamers and streamers take on a completely different vocal identity, including accent changes. Accent Translation is aimed at contact centres that want an American or British accent on a call without discarding the agent's own voice. Isolate suppresses background noise and competing speakers so only the intended speaker is captured. Euphonia targets voice restoration, easing dysphonia and disfluencies for people whose voice no longer matches how they want to sound.

Beyond the self-serve tools, Altered offers premium custom voice cloning work, where the company creates a specific voice for a project. Altered publishes an ethics page and states that consent is required for cloning real people, which matters for anyone using the tools commercially. Pricing is freemium: a free tier and trial are available, paid plans are sold for the software, and custom voice work and enterprise licensing are quoted after contact.

**Pricing & Plans:** Freemium with a free trial. There is a free entry tier, paid subscription plans for Altered Studio and Real-Time Pro, and premium custom voice cloning plus enterprise work priced on request.

- **Real-time voice morphing:** Change your vocal identity on live voice and video calls with minimal latency, using just a handful of CPU cores rather than a dedicated GPU.
- **Accent translation:** Take on an American or British accent while keeping your own vocal character, a feature aimed at contact centres and international client calls.
- **Voice cloning:** Replicate a speaker's voice from a short recording, or commission a fully custom voice for a specific project through Altered's premium service.
- **Studio editing toolkit:** Edit voice inside audio and video files by combining classic DSP effects with modern AI morphing, cloning and text-to-speech inside one application.
- **Voice cleaning and isolation:** Remove background noise, competing speakers, mouth artifacts and filler words, and real-time isolate only the speaker you want heard.

**Strengths:** Two genuinely different products, one tuned for live low-latency use and one for high-fidelity post-production; Unusual accent translation and voice restoration features that most voice changers do not attempt; Publishes an ethics position and requires consent for cloning real people, which helps with commercial compliance; Free tier and trial let you test voice quality before paying

**Limitations:** Studio-grade morphing expects a capable GPU, so hardware requirements are higher than browser-only tools; Free tier is limited, and the most useful professional capability sits behind subscription or a sales conversation; Custom voice cloning is a premium, quoted service rather than a self-serve purchase
