Sprach-Interaktion
Allgemeines[Bearbeiten] Sprach-Interaktion ist ein immer beliebter werdendes Thema, was auch Blinden oder Körperlichbehinderten zu gute kommt. Es ermöglicht das Vorlesen und Diktieren von Texten, sowie das Steuern ganzer Systeme. Definitionen[Bearbeiten] Spracherkennung wird im Allgemeinen mit SR (Speech Recognition) abgekürzt. Sprachsynthese wird im Allgemeinen mit TTS (Text to Speech) abgekürzt.

Free speech recognition in Windows 7 will take surprisingly good dictation
Last 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.

Hidden Markov model
In 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,[7] part-of-speech tagging, musical score following,[8] partial discharges[9] and bioinformatics.

Voice command device
Newer 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.[1] They can understand around 50 different commands and retain up to 2 minutes of vocal messages.[1] 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.[2] 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 Dictation
You 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 service
Telecommunications 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[edit] 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[edit] Voice Carry Over[edit] A common kind of call is Voice Carry Over (VCO). VCO with privacy[edit] 2-Line VCO[edit]
Sprachsteuerung
Als Sprachsteuerung bezeichnet man die Übermittlung von Befehlen an technische Geräte, die per Stimme erfolgt. Grundsätzlich kann das Prinzip der Sprachsteuerung bei einer sehr großen Zahl von Gerätetypen zum Einsatz kommen. Voraussetzung ist, dass es ein Modul für Spracherkennung gibt, das sprachliche Äußerungen aufnehmen und interpretieren kann. Bisherige Einsatzbereiche[Bearbeiten] Sprachsteuerung wird außerdem auch bei Navigationssystemen in Pkws eingesetzt. Softwareauswahl[Bearbeiten] Siehe auch[Bearbeiten]

Spracherkennung
Die Spracherkennung oder auch automatische Spracherkennung ist ein Teilgebiet der angewandten Informatik, der Ingenieurwissenschaften und der Computerlinguistik. Sie beschäftigt sich mit der Untersuchung und Entwicklung von Verfahren, die Automaten, insbesondere Computern, die gesprochene Sprache der automatischen Datenerfassung zugänglich macht. Die Spracherkennung ist zu unterscheiden von der Stimm- bzw. Sprechererkennung, einem biometrischen Verfahren zur Personenidentifikation. Allerdings ähneln sich die Realisierungen dieser Verfahren. Geschichtliche Entwicklung[Bearbeiten] Die Forschung an Spracherkennungssystemen begann in den 1960er Jahren, verlief damals allerdings weitestgehend erfolglos: Die von privaten Firmen entwickelten Systeme ermöglichten unter Laborbedingungen die Erkennung von einigen Dutzend Einzelwörtern. Erst Mitte der 1980er Jahre kam die Entwicklung weiter voran. 2007 wurde die Firma Siri Inc. gegründet und im April 2010 von Apple gekauft. Siehe auch: Stenomaske
