In their own words
Altered Real-Time Pro
Altered Real-Time Pro is a desktop virtual microphone that routes AI-processed speech into voice and video communication apps. It runs on Windows and macOS and works with apps that accept microphone input, including Zoom, Google Meet, Discord, Skype, WhatsApp, games, and call-centre software. Its four feature areas address different audio needs: Isolate suppresses noise and competing speakers, Voice Skins change vocal identity, Accent Translation alters accents, and Euphonia restores voices. Processing can run locally on the user's machine, with the product page saying voice data stays on the PC, or Cloud Compute can offload work to nearby servers in the US, EU, or India. Cloud Compute costs $2 per hour of daily quota per month. The free plan provides 20 minutes of processing per day; paid plans start at $5/mo. Accent-changing effects are designed around 135 ms algorithmic latency, while actual latency depends on the model, CPU, audio settings, and processing cores. Enterprise includes team controls and priority support.
Echo Live
Echo Live changes microphone audio in real time through AI voice conversion and digital signal processing. Its desktop app includes AI voices, live effects, a soundboard, and Voice Lab for making custom effects. The soundboard imports WAV, MP3, OGG, and FLAC files; users can reuse boards and assign hotkeys to individual sounds. Changed audio can go through a virtual microphone or cable for use in Discord, games, OBS, Zoom, and Google Meet.
Echo Lite is a Chrome extension that processes effects, AI voices, and soundboard mixing on-device and connects to supported calling websites. Separate Android and iOS apps offer speech-to-speech conversion, text-to-speech, and voice effects. Echo supports DirectML GPU acceleration on Windows and CoreML on Apple Silicon Macs. The maker says voice processing runs locally and audio is not sent to its servers. The free plan is listed at free. During Alpha, all features are free, though the maker reserves the option to add paid tiers or limits later. Echo Pro is listed without a price.
