Windows Speech Recognition WSR is speech recognition developed by Microsoft for Windows Vista that enables voice commands to control the desktop user interface ; dictate text in electronic documents and email ; navigate websites ; perform keyboard shortcuts ; and to operate the mouse cursor.
It supports custom macros to perform additional or supplementary tasks. WSR is a locally processed speech recognition platform; it does not rely on cloud computing for accuracy, dictation, or recognition, but adapts based on contexts, grammars, speech samples, training sessions, and vocabularies.
It provides a personal dictionary that allows users to include or exclude words or expressions from dictation and to record pronunciations to increase recognition accuracy. Custom language models are also supported. It is present in Windows 7 , Windows 8 , Windows 8. Microsoft was involved in speech recognition and speech synthesis research for many years before WSR.
At WinHEC 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 and discrete command and control. Unlike the speech support included in Windows XP, which was integrated with the Tablet PC Input Panel and required switching between separate Commanding and Dictation modes, Windows Vista would introduce a dedicated interface for speech input on the desktop and would unify the separate speech modes; [17] users previously could not speak a command after dictating or vice versa without first switching between these two modes.
During a demonstration by Microsoft on July 27, —before Windows Vista's release to manufacturing RTM —a notable incident involving WSR occurred that resulted in an unintended output of "Dear aunt, let's set so double the killer delete select all" when several attempts to dictate led to consecutive output errors; [21] [22] the incident was a subject of significant derision among analysts and journalists in the audience, [23] [24] despite another demonstration for application management and navigation being successful.
Reports from early indicated that WSR is vulnerable to attackers using speech recognition for malicious operations by playing certain audio commands through a target's speakers; [26] [27] it was the first vulnerability discovered after Windows Vista's general availability. User Account Control would also prohibit the occurrence of privileged operations. The document harvester, which can analyze and collect text in email and documents to contextualize user terms has improved performance, and now runs periodically in the background instead of only after recognizer startup.
Sleep mode has also seen performance improvements and, to address security issues, the recognizer is turned off by default after users speak "stop listening" instead of being suspended. Windows 7 also introduces an option to submit speech training data to Microsoft to improve future recognizer versions. A new dictation scratchpad interface functions as a temporary document into which users can dictate or type text for insertion into applications that are not compatible with the Text Services Framework.
WSR allows a user to control applications and the Windows desktop user interface through voice commands. When started for the first time, WSR presents a microphone setup wizard and an optional interactive step-by-step tutorial that users can commence to learn basic commands while adapting the recognizer to their specific voice characteristics; [36] the tutorial is estimated to require approximately 10 minutes to complete. WSR is a locally processed speech recognition platform; it does not rely on cloud computing for accuracy, dictation, or recognition.
The WSR interface consists of a status area that displays instructions, information about commands e. The status area represents the current state of WSR in a total of three modes, listed below with their respective meanings:. Colors of the recognizer listening mode button denote its various modes of operation: blue when listening; blue-gray when sleeping; gray when turned off; and yellow when the user switches context e.
The status area can also display custom user information as part of Windows Speech Recognition Macros. An alternates panel disambiguation interface lists items interpreted as being relevant to a user's spoken word s ; if the word or phrase that a user desired to insert into an application is listed among results, a user can speak the corresponding number of the word or phrase in the results and confirm this choice by speaking "OK" to insert it within the application.
An ExactMatchOverPartialMatch entry in the Windows Registry can limit commands to items with exact names if there is more than one instance included in results. Listed below are common WSR commands. Words in italics indicate a word that can be substituted for the desired item e. MouseGrid enables users to control the mouse cursor by overlaying numbers across nine regions on the screen; these regions gradually narrow as a user speaks the number s of the region on which to focus until the desired interface element is reached.
Users can then issue commands including "Click number of region ," which moves the mouse cursor to the desired region and then clicks it; and "Mark number of region ", which allows an item such as a computer icon in a region to be selected, which can then be clicked with the previous click command.
Users also can interact with multiple regions at once. Applications and interface elements that do not present identifiable commands can still be controlled by asking the system to overlay numbers on top of them through a Show Numbers command. Once active, speaking the overlaid number selects that item so a user can open it or perform other operations. WSR enables dictation of text in applications and Windows.
If a dictation mistake occurs it can be corrected by speaking "Correct word " or "Correct that" and the alternates panel will appear and provide suggestions for correction; these suggestions can be selected by speaking the number corresponding to the number of the suggestion and by speaking "OK. Alternatively, users can speak "Spell it" or "I'll spell it myself" to speak the desired word on letter-by-letter basis; users can use their personal alphabet or the NATO phonetic alphabet e.
Multiple words in a sentence can be corrected simultaneously for example, if a user speaks "dictating" but the recognizer interprets this word as "the thing," a user can state "correct the thing" to correct both words at once.
In the English language over , words are recognized by default. A personal dictionary allows users to include or exclude certain words or expressions from dictation. Users can also record pronunciations for words added to the dictionary to increase recognition accuracy; words written via a stylus on a tablet PC for the Windows handwriting recognition feature are also stored. Information stored within a dictionary is included as part of a user's speech profile.
WSR supports custom macros through a supplementary application by Microsoft that enables additional natural language commands. Users and developers can create their own macros based on text transcription and substitution; application execution with support for command-line arguments ; keyboard shortcuts; emulation of existing voice commands; or a combination of these items.
All macros are digitally signed by default if a user certificate is available to ensure that stored commands are not altered or loaded by third-parties; if a certificate is not available, an administrator can create one. For dictation it was found to be Hachman opined that Microsoft does not publicly discuss the feature because of the incident during the development of Windows Vista, with the result being that few users knew that documents could be dictated within Windows before the introduction of Cortana.

Ничего не поделаешь, - вздохнул Стратмор. - Поддержи. Коммандер глубоко вздохнул и подошел к раздвижной стеклянной двери. Кнопка на полу привела ее в движение, и дверь, издав шипящий звук, отъехала в сторону.
