The SR-07 is a fully programmable Speech Recognition circuit that will let you train the system to recognize specific words or vocal commands of your choice. Unlike fixed-command systems, the SR-07 allows user-defined training, making it a flexible solution for a wide variety of applications, including the control of appliances, toys, tools, computers, and more.

Once a word is trained, the SR-07 continuously listens for it. When recognized, the circuit outputs a unique digital binary code corresponding to that word. This output can then be used to trigger external devices through additional interface circuitry.

Key Features Include: Always-on listening mode – No need to press buttons or activate the device manually. User-trainable – Easily program up to 20 or 40 words (depending on configuration). Modular compatibility – Can be embedded into custom designs or used as a standalone unit. Non-volatile memory – Retains trained words even after power-off. PLCC HM2007 chip – Reliable performance from a dedicated speech recognition processor.
