Speech recognition is usually processed in middleware, the results are transmitted to the user applications. In Computer Science and Electrical Engineering speech recognition (SR) is the translation of spoken words into text. It is also known as "automatic speech recognition" (ASR), "computer speech recognition", or just "speech to text" (STT). Some SR systems use "speaker independent speech recognition" while others use "training" where an individual speaker reads sections of text into the SR system. These systems analyze the person's specific voice and use it to fine tune the recognition of that person's speech, resulting in more accurate transcription. Systems that do not use training are called "speaker independent" systems. Speech recognition applications include voice user interfaces such as voice dialling (e.g. The term voice recognition or speaker identification refers to finding the identity of "who" is speaking, rather than what they are saying.

Free speech recognition in Windows 7 will take surprisingly good dictationLast month I experienced a hard disk failure and bought a new machine. In the process I lost my copy of Dragon Naturally Speaking. I have purchased this software and have the CD somewhere, but we moved since I last installed it and I have no idea where the CD is. I like to use a speech recognition program like Dragon sometimes. I had just such an occasion this week, and without my copy of Dragon I was kind of stuck. To turn on speech recognition, click the Start button (bottom left corner by default), choose the “Help & Support” option and type in “Set up Speech Recognition” or just “Speech Recognition” to see how to set it up. I set it up and did not train it at all. A demo: This article is also interesting: Talk to the Machine: Progress in Speech-Recognition Software, by David Pogue How close are we to the Star Trek ideal of conversational computers that never get it wrong?
Hidden Markov modelIn simpler Markov models (like a Markov chain), the state is directly visible to the observer, and therefore the state transition probabilities are the only parameters. In a hidden Markov model, the state is not directly visible, but output, dependent on the state, is visible. Each state has a probability distribution over the possible output tokens. Therefore the sequence of tokens generated by an HMM gives some information about the sequence of states. Note that the adjective 'hidden' refers to the state sequence through which the model passes, not to the parameters of the model; the model is still referred to as a 'hidden' Markov model even if these parameters are known exactly. Hidden Markov models are especially known for their application in temporal pattern recognition such as speech, handwriting, gesture recognition, part-of-speech tagging, musical score following, partial discharges and bioinformatics.

MARF -- Modular Audio Recognition Framework and its Applications for Speech, Voice, and NLP ProcessingVoice command deviceNewer VCDs are speaker-independent, so they can respond to multiple voices, regardless of accent or dialectal influences. They are also capable of responding to several commands at once, separating vocal messages, and providing appropriate feedback, accurately imitating a natural conversation. They can understand around 50 different commands and retain up to 2 minutes of vocal messages. VCDs can be found in computer operating systems, commercial software for computers, mobile phones, cars, call centers, and internet search engines such as Google. In 2007, a CNN business article reported that voice command was over a billion dollar industry and that companies like Google and Apple were trying to create voice recognition features. It has been years since the article was published, and since then the world has witnessed a variety of voice command devices.

Use Google Chrome as a Free Voice Recognition Software with DictationYou can use Google Chrome as a free voice recognition software to write longer emails and documents without even installing anything on your Windows or Mac computer. Meet Dictation v2.0, a web-based speech recognition app that will transcribe your voice into digital text using the Chrome Speech API. You can also install Dictation as a Chrome App. Unlike the regular Chrome web apps that are nothing but fancy bookmarks, the Dictation App for Chrome will run entirely on your computer. Getting started with Dictation in simple. Say “new sentence” to begin a new sentence. If you make a mistake, or if Chrome makes an error while recognizing your speech, simple click the incorrect word and edit it inline. Dictation 2.0 – What’s New The first release of Dictation happened in August 2012 and much has changed since then. The new version of Dictation App does sport a few extra features. Also, you can now export your transcriptions to Dropbox and Google Drive from Dictation itself.
Telecommunications relay serviceTelecommunications Relay Service, also known as TRS, Relay Service, or IP-Relay, or Web-based relay services, is an operator service that allows people who are deaf, hard-of-hearing, deafblind, or have a speech disorder to place calls to standard telephone users via a keyboard or assistive device. Originally, relay services were designed to be connected through a TDD (TTY) or other assistive telephone device. Services have gradually expanded to include almost any real-time text capable technology such as a personal computer, laptop, mobile phone, PDA, and many other devices. The first relay service was established by Converse Communications of Connecticut in 1974. Types of service available Depending on the technical and physical abilities, as well as physical environments, of users, different call types are possible via relay services. TTY to Voice/Voice to TTY Voice Carry Over A common kind of call is Voice Carry Over (VCO). VCO with privacy 2-Line VCO
Comparison of optical character recognition softwareThis comparison of optical character recognition software includes: OCR engines, that do the actual character identificationLayout analysis software, that divide scanned documents into zones suitable for OCRGraphical interfaces to one or more OCR enginesSoftware development kits that are used to add OCR capabilities to other software (e.g. forms processing applications, document imaging management systems, e-discovery systems, records management solutions)
