Speech recognition lets robots understand spoken commands. Powered by deep learning, now accurate even in Indian-language and accent variations.
The human robot interaction concept: Speech recognition lets robots understand spoken commands. Powered
Automatic Speech Recognition (ASR) converts spoken audio into text. In robotics it enables voice control of robots — from saying 'pick up the cup' to an Indian-language voice for elderly-care robots.

Speech Recognition for Robots
What is Speech Recognition for Robots?
Automatic Speech Recognition (ASR) converts spoken audio into text. In robotics it enables voice control of robots — from saying 'pick up the cup' to an Indian-language voice for elderly-care robots.
How It Works
Modern ASR systems use deep neural networks. Audio is first converted to a mel-spectrogram. An encoder (often a transformer) compresses the spectrogram into hidden representations. A decoder (CTC, RNN-T, or transformer) predicts the most likely text. Recent open-source models (OpenAI Whisper, Meta SeamlessM4T) handle 100+ languages including Hindi, Tamil, and Bengali with high accuracy.
Real-World Example
Alexa, Siri, Google Assistant — all ASR. Indian voice startups (Reverie, AI4Bharat's IndicSUPERB models) build Indian-language ASR. Service robots in airports use ASR for directions. Robotic surgery now uses ASR for hands-free instrument commands.
Why It Matters for Robotics
Voice is the most natural human interface. As India's smartphone-first population skews to voice over text, robotics that listen well will dominate. India-specific ASR (regional accents, code-mixing) is a hot startup space.
Try It Yourself
Install OpenAI Whisper (pip install openai-whisper). Run it on a 30-second audio clip in Hindi or any Indian language — accuracy is impressive. Plug it into a ROS2 node that publishes recognised text on a topic, and a robot can listen.
