Voice Control at Your Fingertips: The Top 10 Free Speech-to-Text APIs that you can use in your next IoT Project

Speech-to-text technology, also known as automatic speech recognition (ASR), is a technology that converts spoken language into written text. This technology has many applications, including voice-controlled devices, transcription services, and accessibility for people with speech impairments. And it can also be used in IoT, by adding voice-controlled capabilities to your IoT devices, such as smart home automation, voice-controlled robots, smart speakers and many other applications.

Some of the most popular free speech-to-text APIs include Google Cloud Speech-to-Text API, Microsoft Azure Speech Services, IBM Watson Speech to Text, Sphinx, Amazon Transcribe, Houndify, Speechmatics, Deep Speech and OpenVINO. These APIs can help you to build more intelligent and user-friendly devices, by providing you with the ability to understand natural language commands, transcribe speech to text, and convert text to speech, which can help to make your IoT devices more accessible and easy to use. For example, you can use speech-to-text technology to create a voice-controlled smart thermostat that can adjust the temperature of your home based on your spoken commands, or you can use it to build a voice-controlled robot that can navigate and perform tasks in your home or office.
