## 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

## Fish Audio

Fish Audio, originally known as Fish Speech, is a voice-AI platform for turning text into natural speech. It combines text-to-speech, voice cloning and speech-to-text with emotional control, so you can tag a line as [whispering], [excited] or [sobbing] and get delivery that matches the script rather than flat narration. The voice library is enormous, with community-uploaded voices numbering in the millions across a wide range of languages.

Cloning is fast and forgiving: a short sample is enough to build a usable voice model, and it can then speak in many languages while keeping the original timbre. Fish Audio publishes powerful APIs for real-time streaming, cloning and transcription, and positions itself for enterprise work such as conversational agents, dubbing and audiobook production.

The company also keeps an open-source arm, releasing the Fish Speech model line for self-hosting, while the hosted platform adds a browser studio, avatar and image/video model integrations, and paid tiers for higher volume. Free starting tiers make it easy to evaluate before committing.

**Pricing & Plans:** Freemium: free sign-up with monthly generations, plus paid subscriptions for higher volume, commercial use and API access; enterprise pricing on request.

- **Expressive Text to Speech:** Type or paste a script and generate natural narration, with inline emotion and delivery tags such as [whispering], [angry] or [laughing].
- **Instant Voice Cloning:** Create a usable voice clone from a short audio sample and reuse it across scripts and languages.
- **Huge Voice Library:** Browse and use a large catalog of community voices covering many languages and character styles.
- **Speech to Text:** Transcribe audio with multilingual support and emotion or speaker cues for downstream editing.
- **Real-time Voice APIs:** Low-latency streaming endpoints let developers build conversational agents, dubbing pipelines and audio apps.

**Strengths:** Natural, emotionally controllable output that handles nuance well; Voice cloning works from a very short sample; Very large shared voice library plus open-source model lineage; Robust APIs for real-time streaming and developer integration

**Limitations:** Free tier is limited and top-quality usage pushes you toward paid plans; Voice cloning raises consent and impersonation risks that teams must manage; Some features and model names change quickly, so docs can lag the product
