Introduction
Ordinary voice recognition systems lack sound source identification capability, resulting in monotonous one-dimensional interaction logic. Within the AI & Smart Integration category, this article introduces dual-ear voice positioning technology and describes directional auditory simulation that conforms to human interaction habits.
Defects of Non-Directional Voice Recognition
Single-microphone voice systems cannot identify sound source directions. The doll maintains an unchanged response posture regardless of the user’s speaking position, lacking natural human auditory interaction logic.
Dual-Ear Bionic Microphone Layout
Two high-sensitivity noise-canceling microphones are symmetrically embedded in bionic ears. The dual-channel sound receiving structure simulates human binaural auditory positioning principles.
Sound Source Calculation Algorithm
The AI algorithm calculates sound source angles based on tiny time differences between dual-channel sound signals, accurately identifying the user’s speaking direction within a 180° horizontal sensing range.
Directional Head Rotation Response
After capturing sound source data, the silent skeleton slowly rotates its head toward the sound source. Natural directional gazing simulates human listening habits, improving interaction immersion and humanized response authenticity.
Immersive Conversational Atmosphere
Directional voice positioning eliminates flat mechanical interaction. Active gazing and targeted responses restore real human conversation scenarios. For high-end collectors pursuing subtle humanized details, binaural auditory technology optimizes intimate daily communication experience.
