| API | An API is available to Enterprise customers for integrating Altered Studio into other systems. | The App development workflow starts a local API on port 8000 alongside a web UI on port 3000, and the Python app can mount a FastAPI realtime API. |
| Integrations | The online Voice Editor can work with audio files in Google Drive, and RealTime Pro routes audio through a virtual microphone to apps including Discord, Zoom, Microsoft Teams, and Google Meet. | Official download materials link Google Colab, Pinokio and Hugging Face as cloud or one-click launch options. |
| Product | Altered Studio combines multiple Voice AI technologies in one platform for creating professional voice content. | Applio is an open-source AI voice conversion suite for creating covers, training custom voice models, and converting voices in real time. |
| Self-hosting | Enterprise deployments can use on-premise compute, and local servers can keep processing traffic inside an intranet. | The Python repository includes Dockerfiles and Compose configuration for self-hosted deployments. |
| Text-to-speech | Text-to-speech offers more than 70 languages and third-party voices from Azure, Google, AWS Polly and IBM. | Text can be synthesized with Edge TTS and then converted through an RVC model. |
| What it does | Altered Studio combines speech-to-speech voice morphing, text-to-speech, cloning, transcription, translation, dubbing and audio editing in one platform. | Applio is an open-source AI voice-conversion suite for creating covers, training voice models and converting voices in real time. |

In their own words
Altered Studio
Altered Studio combines voice transformation and audio production tools for creating professional voice content. Its Speech-to-Speech and Performance-to-Performance morphing changes a voice while retaining the speaker’s performance. Other tools include text-to-speech, voice cloning, AI voice cleaning, denoising, audio editing, DSP effects and batch processing. Studio supports transcription and translation in 75+ languages, and text-to-speech voice-over in 70+ languages. A Rapid Voice Clone can be made from 4–8 seconds of audio; custom voice models are available by contacting Altered. The online Voice Editor can work with Google Drive audio, while RealTime Pro routes audio through a virtual microphone to apps including Discord, Zoom, Microsoft Teams and Google Meet. The free plan includes 3 minutes per month of voice morphing and 10,000 AI tokens. Creator costs $30 a month billed annually; Professional costs $90 a month billed annually. Desktop use requires a Windows PC with an 8GB+ Nvidia GPU, and mobile devices are not currently supported.
Applio
Applio is an open-source AI voice conversion suite for making covers, training custom voice models, and changing voices in real time. It can convert recorded audio with ready-made models, plus pitch tuning, cleanup, upscaling, and batch processing. Live conversion is intended for songs, streams, and calls. Model tools include training, a voice blender, text-to-speech, and an audio analyzer for dataset readiness. Applio supports Linux, macOS, Windows, web, and self-hosted use; Google Colab, Pinokio, and Hugging Face are also listed as ways to run it. Its plan is free, with no accounts or paywalls. The MIT license permits personal, research, and commercial use. The maker says audio and models remain on the device unless shared, and core features do not require an account, telemetry, or cloud dependency. Documentation recommends an Nvidia RTX 20-series GPU or newer for local voice training; most modern computers can handle inference with existing models.
