Lingxin: a no-code platform to design robot voice, behavior and persona

Chinese company Logic Robotics has unveiled the Lingxin platform, which lets users with no coding background effectively assemble a robot’s personality. Through a straightforward interface, they can adjust voice, temperament, behavior, memory, and even assign roles and tasks. The platform comes with 30–40 preset voice styles, ranging from a gentle, companion-like tone to playful or dialect-inflected delivery. There’s also a voice replication feature: upload a short sample, and the robot can speak in a voice very close to your own.

Particular emphasis is placed on behavior and emotion. Users can mix facial expressions, gestures, and lines to craft unique greeting routines, a praise mode, or even mini-performances. Editing works much like trimming a video clip, which makes experimentation feel natural rather than technical. The platform also lets you set a robot’s persona with a single sentence, after which the system selects a matching communication style. Traits such as aloof or rational can be chosen manually, turning the device into a character that remembers preferences and past requests.

For businesses, the platform supports uploading company materials, training scripts, and work instructions so the robot can act as a consultant, guide, or support agent while continuously refining its responses and skills. An update for supported models is expected in the near future.
