## 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

## HeyGen

HeyGen removes the biggest bottlenecks in corporate video production: cameras, talent, studios and reshoots. You start from a script, slide deck or PDF, choose one of hundreds of ready-made stock presenters or train a custom avatar from your own footage, and the platform generates a talking-head video with synchronized lip movement. Because the avatar is a model rather than a filming session, updating a sentence in a compliance training module or a product launch script means regenerating text, not booking a studio day.

Localization is where HeyGen is strongest. Videos can be translated and dubbed into more than 175 languages and dialects, with editable translation scripts, brand glossaries, the option to switch or upload voices, and proofreading seats so a native speaker can validate the output. The Video Agent and Avatar engines handle longer-form content, 4K export on higher tiers, cinematic avatar scenes and motion or gesture control. Beyond plain generation, HeyGen supports interactive video with quizzes, branching, video-link embedding and SCORM export for learning management systems, which is why it is widely used in L&D and enablement.

Team and enterprise features include shared workspaces, a brand kit and asset library, comment and draft collaboration, SAML/SSO, SCIM provisioning and MFA, plus integrations with Zapier, Make, n8n and HubSpot. There is also an API and a ChatGPT plugin. Pricing follows a freemium structure: a free tier with watermarked videos, then Creator, Pro, Business and custom Enterprise plans billed monthly or annually.

**Pricing & Plans:** Freemium with tiered subscriptions. The Free plan is $0 and allows up to 3 watermarked videos a month of up to 1 minute each. Creator is $29/month, Pro (most popular) is $49/month, and Business is $149/month for teams, with additional seats around $20/seat/month. Annual billing offers roughly two months free. Enterprise pricing is quoted via sales, and API usage is billed separately.

- **AI avatars from text:** Choose from 500+ stock presenters, use photo avatars, or train a custom Video Avatar that looks and sounds like you, then generate narrated videos straight from a script.
- **Video translation and dubbing:** Localize one recording into 175+ languages and dialects with editable scripts, brand glossaries, voice switching and proofreading seats for native-language review.
- **Video Agent and frontier models:** An agentic workflow expands ideas into finished videos, with access to leading generative models for video and image generation on higher plans.
- **Interactive and LMS-ready video:** Add quizzes, branching and decision points, embed videos by link, and export SCORM packages so content drops straight into corporate learning systems.
- **Team workspaces and security:** Shared workspaces, brand kits, asset libraries, draft collaboration, SAML/SSO, SCIM provisioning and MFA cover the governance needs of larger organisations.

**Strengths:** Removes the need for cameras, studios and on-camera talent, dramatically cutting video production time; Broad localization support covering 175+ languages and dialects with editable scripts; Strong enterprise readiness including SSO, SCIM, brand controls and LMS integrations; Free tier and annual discounts let teams test the workflow before committing

**Limitations:** Credits are the real constraint: heavy usage on higher-resolution exports burns through them quickly; Avatar realism can still fall into the uncanny valley for some viewers and use cases; Serious production volume requires a paid plan, and enterprise pricing is quote-only
