## 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

## Applio

Applio is an open-source toolkit for everything you might want to do with a voice. At its core is VITS-based voice conversion: feed it an audio file and a trained voice model and it rewrites the audio in that voice, with controls for pitch, cleanup, upscaling and batch processing. A realtime mode does the same job on live microphone input with low enough latency for singing, streaming and calls, and a text-to-speech module lets you write a script, pick a source voice and run the generated speech through your voice models.

Training your own voice is a first-class workflow rather than an afterthought. You prepare a dataset of audio clips, run preprocessing and feature extraction, and choose automatic or manual training before exporting a model you can reuse. Supporting tools include a voice blender that merges several models into a single new voice with adjustable contribution from each, and an audio analyzer that reports audio health so you can check dataset readiness before spending hours training.

The project ships as a standalone desktop app and as a classic Gradio WebUI, spanning Windows, macOS and Linux. Everything runs on your own machine, which matters for privacy and for anyone working with voice data they would rather not upload. There is no account system and no telemetry, the code is auditable, and the license is MIT, so personal, research and commercial use are all permitted. A community playground lets you try shared voice models before downloading anything.

**Pricing & Plans:** Completely free and open source under the MIT license. There are no subscription tiers, no credit systems and no paid plans; optional community support is offered through Ko-fi donations.

- **Voice conversion:** Turn any audio clip into another voice using ready-made models, with pitch tuning, audio cleanup, upscaling and batch processing.
- **Real-time voice changing:** Route your microphone through a model with low-latency inference for live singing, streaming and voice calls.
- **Custom model training:** Prepare a dataset, extract features and train your own voice model using automatic or fully manual training pipelines.
- **Voice blender:** Mix several trained voice models into one new voice, with fine control over how much each contributor influences the result.
- **Text-to-speech and audio analyzer:** Generate speech from written text, then run it through voice models, and inspect dataset audio health before you train.

**Strengths:** Free and open source under MIT, with no accounts, paywalls or telemetry; Runs fully locally on Windows, macOS and Linux for privacy; Covers the full workflow: conversion, realtime, text-to-speech and training; Backed by an active community with shared voice models and open discussion

**Limitations:** Getting good results depends on dataset quality and training hardware such as a capable GPU; The standalone app and web UI still require some technical setup for training; Voice cloning raises consent and impersonation concerns that users must handle responsibly
