Virtual voice builderv1.0.0

A Node.js developer pipes their microphone through Deepgram STT, an LLM for tone or persona rewriting, and a TTS voice, then sends the resulting PCM into a virtual cable so Google Meet, Zoom, or Discord transmits the AI voice. Useful for streamers, sales reps, and creators who want a consistent synthetic persona without specialized hardware.

Contact centers intercept agent audio, run live transcription and LLM assistance, and synthesize a standardized brand voice back into the same call path. The pipeline enforces script compliance and consistent tone while keeping CRM transcription in sync.

Users with motor or speech disabilities speak short phrases into a microphone, and the system reconstructs fluent, natural-sounding speech through an LLM and TTS, injecting it into video conferencing apps via virtual audio. This provides a real-time assistive layer without requiring platform-specific plugins.

Meeting participants speak in their native language; the pipeline transcribes, translates with an LLM, and speaks the result in a cloned or standard voice into the conference call. Remote teams can hear near-real-time translation through Google Meet or Teams.

Producers route recorded or live mic input through the pipeline to produce synthetic narration in a chosen voice, writing decoded PCM directly to an audio interface for recording. The kill switch allows instant manual takeover during live sessions.

Offer a hosted dashboard where streamers and podcasters configure STT, LLM persona prompts, and TTS voices, then receive a local virtual audio endpoint. Pricing tiers by monthly processing minutes and number of saved voice profiles.

License the pipeline as an SDK/API to contact centers and enterprise collaboration teams, including compliance logging, SSO, and on-prem deployment options. Integration into existing telephony or meeting infrastructure drives seat-based contracts.

Sell metered API access to the pipeline components (device discovery, resampling, sentence chunking, TTS routing) so other developers can build voice apps without managing ffmpeg or virtual cable quirks. Usage-based pricing per minute of processed audio.
