A voice browser is a web browser that presents an interactive voice user interface to the user. In addition, it typically provides and interface to the PSTN or a PBX. Just as a visual web browser works with HTML pages, a voice browser operates on pages that specify voice dialogues. Typically these pages are written in VoiceXML, the World Wide Web Consortium s standard voice dialog markup language, but other proprietary voice dialogue languages remain in use.

A voice browser presents information aurally, using pre-recorded audio file playback or using text-to-speech software to render textual information as audio. A voice browser obtains information by advanced speech recognition software, keypad entry (e.g., DTMF) and recorded speech.

As speech recognition and web technologies have matured over the past decade, thousands of voice applications have been deployed commercially and in many cases voice browsers are supplanting traditional proprietary interactive voice response systems. Scores of companies provide voice browsers. These take the form of software, packaged hardware/software solutions or hosted solutions.
