Knowledge Base

Frequently Asked Questions (FAQ)

In-depth insights into voice interaction system integration, noise shielding, and system deployment.

How does the system eliminate robot joint and servo motor noise from speech signals?
We implement an Active Structural Vibro-Acoustic Cancellation (ASVAC) architecture. By feeding servo telemetry, current loads, and known joint velocity profiles directly into the adaptive filtering algorithm, the DSP dynamically predicts and subtracts internal harmonic mechanical noise before audio frames reach the neural speech recognizer.
Can the voice interaction framework execute in full offline/air-gapped environments?
Yes. For critical defense, medical, and proprietary manufacturing settings, we supply a standalone edge stack utilizing quantized 8-bit SLU models running locally on RK3588, Jetson Orin, or dedicated NPU modules. Core control commands, safety stops, and local task workflows run with zero external network connectivity.
What hardware form factors are supported for customized robot head enclosures?
Our China manufacturing partner ecosystem designs both circular (4 to 8 mic) planar arrays and custom 3D spherical topologies that integrate cleanly into humanoid head shells, dog-robot chest plates, or industrial terminal bezels, accompanied by complete acoustic chamber simulation files (STEP and STL).
How is lip-synchronization and facial animation handled during speech generation?
The neural TTS pipeline outputs time-aligned phonetic tokens alongside raw audio streams. These are mapped in real time to ARKit blendshapes or facial motor controller positions at 60 Hz, ensuring zero perceptible drift between synthetic voice delivery and physical robotic or digital human mouth articulation.
