• No Recognizer Is Installed
• No Recognizer Is Installed C#

So I'm working on a c# app that uses Text To Speech and Automatic Speech Recognition, in Visual Studio 2015 on Windows 10. I'm using System.Speech for Synthesis (TTS) and Microsoft.Speech for Recognition (ASR). I can't use Microsoft for Synthesis because it will tell me there are no voices installed.

• SpeechRecognitionEngine.InstalledRecognizers returns No recognizer installed 1 answer

I tried to recognition speech in C# but it began bad. I had followed some tutorials in YouTube but this error appear every time. So I got the Microsoft MSDN code and I tried to find some solutions in Google. This is the code I'm using:

I already downloaded the Microsoft Speech Platform SDK and the Runtime Languages (US). The error persists.

I also already had used this code, as I saw in a topic here in StackOverflow:

It didn't work, so I tried to use this (as I saw in MSDN):

When I tried to use those codes, the error change and say: 'No recognizer of the required ID found'.I use the Windows 7 (Home Basic, x64), Microsoft Visual C# 2010 Express. My default language (the system language also is) is Portuguese (Brazil), maybe it's the error cause?Well, thats it, I hope I wrote all detailed for you understand. Sorry for my english I'm training this, haha :P

Definition

Overloads

Remarks

You can construct a SpeechRecognitionEngine instance from any of the following:

• The default speech recognition engine for the system

• A specific speech recognition engine that you specify by name

• The default speech recognition engine for a locale that you specify

• A specific recognition engine that meets the criteria that you specify in a RecognizerInfo object.

Before the speech recognizer can begin recognition, you must load at least one speech recognition grammar and configure the input for the recognizer.

To load a grammar, call the LoadGrammar or LoadGrammarAsync method.

To configure the audio input, use one of the following methods:

SpeechRecognitionEngine()SpeechRecognitionEngine()SpeechRecognitionEngine()

Initializes a new instance of the SpeechRecognitionEngine class using the default speech recognizer for the system.

Remarks

Before the speech recognizer can begin speech recognition, you must load at least one recognition grammar and configure the input for the recognizer.

To load a grammar, call the LoadGrammar or LoadGrammarAsync method.

To configure the audio input, use one of the following methods:

SpeechRecognitionEngine(CultureInfo)SpeechRecognitionEngine(CultureInfo)SpeechRecognitionEngine(CultureInfo)SpeechRecognitionEngine(CultureInfo)

Initializes a new instance of the SpeechRecognitionEngine class using the default speech recognizer for a specified locale.

Parameters

culture

CultureInfoCultureInfoCultureInfoCultureInfo

The locale that the speech recognizer must support.

Exceptions

None of the installed speech recognizers support the specified locale, or culture is the invariant culture.

Culture is null.

Examples

The following example shows part of a console application that demonstrates basic speech recognition, and initializes a speech recognizer for the en-US locale.

Remarks

Microsoft Windows and the System.Speech API accept all valid language-country codes. To perform speech recognition using the language specified in the CultureInfo argument, a speech recognition engine that supports that language-country code must be installed. The speech recognition engines that shipped with Microsoft Windows 7 work with the following language-country codes.

• en-GB. Beck mellow gold rar. English (United Kingdom)

• en-US. English (United States)

• de-DE. German (Germany)

• es-ES. Spanish (Spain)

• fr-FR. French (France) Ousama game shuukyoku.

• zh-CN. Chinese (China)

• zh-TW. Chinese (Taiwan)

No Recognizer Is Installed

Two-letter language codes such as 'en', 'fr', or 'es' are also permitted.

Before the speech recognizer can begin recognition, you must load at least one speech recognition grammar and configure the input for the recognizer.

To load a grammar, call the LoadGrammar or LoadGrammarAsync method.

To configure the audio input, use one of the following methods:

SpeechRecognitionEngine(RecognizerInfo)SpeechRecognitionEngine(RecognizerInfo)SpeechRecognitionEngine(RecognizerInfo)

Initializes a new instance of the SpeechRecognitionEngine using the information in a RecognizerInfo object to specify the recognizer to use.

Parameters

recognizerInfo

RecognizerInfoRecognizerInfoRecognizerInfoRecognizerInfo

The information for the specific speech recognizer.

Examples

The following example shows part of a console application that demonstrates basic speech recognition, and initializes a speech recognizer that supports the English language.

Remarks

You can create an instance of this class for any of the installed speech recognizers. To get information about which recognizers are installed, use the InstalledRecognizers method.

Before the speech recognizer can begin recognition, you must load at least one speech recognition grammar and configure the input for the recognizer.

To load a grammar, call the LoadGrammar or LoadGrammarAsync method.

SpeechRecognitionEngine(String)SpeechRecognitionEngine(String)SpeechRecognitionEngine(String)SpeechRecognitionEngine(String)

Initializes a new instance of the SpeechRecognitionEngine class with a string parameter that specifies the name of the recognizer to use.

Parameters

recognizerId

StringStringStringString

The token name of the speech recognizer to use.

Exceptions

No speech recognizer with that token name is installed, or recognizerId is the empty string (').

recognizerId is null.

Examples

The following example shows part of a console application that demonstrates basic speech recognition, and creates an instance of the Speech Recognizer 8.0 for Windows (English - US).

Remarks

The token name of the recognizer is the value of the Id property of the RecognizerInfo object returned by the RecognizerInfo property of the recognizer. To get a collection of all the installed recognizers, use the static InstalledRecognizers method.

Before the speech recognizer can begin recognition, you must load at least one speech recognition grammar and configure the input for the recognizer.
