Real-time voice AI APIs with 50 ms to first audio
Text-to-speech, speech-to-text, and live speech-to-speech translation reach roughly 50 ms to first audio, tuned for conversational agents rather than batch processing.
Clone a voice from a short sample for everyday use, move up to pro cloning for production quality, or generate a brand-new voice from a text description.
WebSocket streaming, Python and Rust SDKs, custom vocabulary, semantic VAD, and code-switching support make integration straightforward for agent builders.
Phonon is Gradium's openly available TTS model that runs on-device for offline or privacy-sensitive deployments.

Instant AI background removal for high-resolution portraits, e-commerce product catalogs, and automated API workflows.
Automatically separates foreground subjects from complex backgrounds with hair-level edge precision, exporting transparent PNGs or custom solid and scenic backdrops up to 50 megapixels.
Integrate automated background cutouts into e-commerce platforms, mobile apps, and photo booths with cloud processing speeds of up to 500 images per minute.
Remove backgrounds directly inside Photoshop with a single click, returning a non-destructive editable layer mask for fine-tuning complex studio composites.
Drag and drop entire folders of product photography or portrait shoots for unattended batch processing with preset output dimensions and background templates.
