Puheohjattua

Puheohjattua is a Finnish adjective used to describe systems, interfaces or processes that are controlled through spoken language. The term derives from puhe (speech) and ohjattua (guided) and appears in Finnish technical literature as a way to distinguish voice-driven interaction from manual input. In practice, puheohjattua can refer to hardware devices with voice control, software interfaces that are navigated by spoken commands, or work processes that are guided by spoken instructions.

In human-computer interaction, puheohjattua describes voice interfaces for smartphones, smart speakers, vehicles, and assistive technologies. Examples include voice-activated assistants, hands-free control of navigation or home automation, and educational tools that respond to spoken input. In industrial and professional settings, puheohjattu control may enable hands-free operation of machinery, medical devices, or workflow software, typically relying on speech recognition and natural language processing.

Common challenges include recognition accuracy in noisy environments or with diverse accents, privacy and data-security concerns, latency, and the need for reliable fallback methods when recognition fails. The term is used mainly in Finnish-language sources and remains one of several phrases—such as voice control or speech-driven interfaces—used to describe similar capabilities in English-language literature.
