Dictaphone wax cylinder dictation machine Dictaphone on display in a museum. Dictaphone was an American company founded by Alexander Graham Bell that produced dictation machines. It is now a division of Nuance Communications, based in Burlington, Massachusetts.
A prototype speech recognition Aero Wizard in Windows Vista (then known as "Longhorn") build 4093.. At WinHEC 2002 Microsoft announced that Windows Vista (codenamed "Longhorn") would include advances in speech recognition and in features such as microphone array support [8] as part of an effort to "provide a consistent quality audio infrastructure for natural (continuous) speech recognition ...
Transcribing dictation with a Dictaphone wax cylinder dictation machine, in the early 1920s. Note supply of extra wax cylinders on lower part of stand. A dictation machine is a sound recording device most commonly used to record speech for playback or to be typed into print.
Dragon NaturallySpeaking uses a minimal user interface. As an example, dictated words appear in a floating tooltip as they are spoken (though there is an option to suppress this display to increase speed), and when the speaker pauses, the program transcribes the words into the active window at the location of the cursor.
Speech recognition is an interdisciplinary subfield of computer science and computational linguistics that develops methodologies and technologies that enable the recognition and translation of spoken language into text by computers. It is also known as automatic speech recognition (ASR), computer speech recognition or speech-to-text (STT).
At a meeting with financial analysts in July 2000, Microsoft demonstrated Office XP, then known by its codename, Office 10, which included a subset of features Microsoft designed in accordance with what at the time was known as the .NET strategy, one by which it intended to provide extensive client access to various web services and features such as speech recognition.

It uses inverse filtering trained on non-speech segments to filter out background noise, so that it can then more reliably use a simple power-threshold to decide if a voice is present. [ 5 ] The G.729 standard calculates the following features for its VAD: line spectral frequencies , full-band energy, low-band energy (<1 kHz), and zero-crossing ...
Electrodes used in subvocal speech recognition research at NASA's Ames Research Lab. Subvocal recognition (SVR) is the process of taking subvocalization and converting the detected results to a digital output, aural or text-based. [1]
