Deep Dive into Six Core Functional Modules
Acoustic Front-End Signal Engine
Built-in high-precision VAD endpointing, AEC echo cancellation, and NS ambient noise suppression filter out mall, in-vehicle, and street background chatter.
Domain-Boosted Streaming ASR
Supports custom hotword boosting for SKU codes, industry jargon, and proprietary terms — transcribing in real time while sharply reducing homophone errors.
Low-Latency Natural Barge-In
Intelligently distinguishes polite backchanneling ('uh-huh', 'okay') from genuine interruptions, pausing playback immediately to listen.
Asynchronous Tool Calling
Queries order, inventory, and ticket APIs concurrently in the background while maintaining natural conversational flow — eliminating awkward lookup silence.
Customer-Level Long-Term Memory
Retains prior call outcomes, preferred callback windows, and open action items across sessions so customers never have to repeat themselves.
100% Compliance QA & Hard-Case Flywheel
Automatically generates QA scorecards, sensitive-term alerts, and hard-case sample pools to drive weekly ASR and script iteration.
