VB 2010 Speech Recognition / Speech-To-Text / Voice Control

Oct 23, 2011

I'm trying to create a Speech Recognition support for my program. I want to make it so that if I say something in my microphone, the program just writes what I said in Label1. I looked for Speech Recognition codes in MSDN and Google, but I didn't find anything useful. I found a code, but it was for VB.net, I tried but it didn't work in VB 2010.


Use Speech Recognition With Voice Only Triggering Commands In The Program?

Aug 11, 2010

I am using system.speech currently. I want to use speech recognition to make a program. However, while the program is running, I noticed that some of the commands for windows (like saying "run") would trigger other program functions. Thus, while the VB.net program is running I do not want this to happen. Also, when the computer starts up, I speech to start listening right away rather than me having to say "start listening". How can I do this? I am pretty sure that it is simple. This is my code so far:

Add Speech Recognition Capabilities?

Oct 14, 2006

I'm working on a program that needs Speech Recognition and every website says to download the Microsoft Speech Recognition Engine. I can't find that, but I've downloaded all the SDKs. Are they the same? And it always says to add a speech recognition component to the form, but I can't find where that is in Visual Basic 2005. I'm using the Express Edition, but I don't think that matters.

Getting The Speech Recognition Code?

May 25, 2009

what I gather, the biggest difference between the old SAPI 5.1 and SAPI 5.3 is that SAPI 5.3 actually takes less code to do some of the same things that SAPI 5.1 does. This is just a simple example that runs notepad and says it is before doing so.One thing to remember is that the name of speech lib is changed again. Now you have to do this: Project -> Add Reference -> .NET -> System.Speech

imports system.speech
Public Class Form1
Public WithEvents recognizer As New System.Speech.Recognition.SpeechRecognitionEngine
Dim gram As New System.Speech.Recognition.DictationGrammar()


gram is a DictationGrammar object. As it turns out, there are two grammar objects in SAPI 5.3. As you've probably already guessed, DictationGrammar is for spoken language and the normal grammar object is for simple grammar rules.

So basically, Load the grammar, set audio to the default input device and then start an Async recognize call. They have a blocking recognize call and one thing to note here is that it will turn itself off after each sucessful recognized phrase. Meaning that you have to recall Async recognize at the end of the GotSpeech sub if you want to keep picking up voice commands. As it stands, this will pick up one command and no more because it stops recognition.

One neat thing about the synthesis engine is that you can specify things like ".NET" to be said as "dot net" by Anna. Also, as it stands, the periods aren't said and so are pretty much useless. It acts just like the Vista Recognition engine also so if you spell out a word, Anna will spell it out too.In this example there is an undeclared variable named "cmd" that I fail to understand. What is the role of it and where does it obtain it's value from. I actually assume it should be the one to get the decoded\recognized text from the recognizer but not sure how that is achieved.

Speech Recognition For Numbers

May 11, 2011

I'm using Speech.Recognition.SpeechRecognizer in VB.NET 2010 on XP-SP3. I can't figure out how to get it to recognize a number as a number. I want to be able to say "five" and have the code interpret it as the value 5 instead of the word. I know I could use a long choices array or sementics key/value combintations as I have for other conditions but that would be a considerable amount of hard coding or XML work. Is there a more efficient way to get the desired result?

Speech Recognition From Own Grammar

Jul 18, 2010

I'm making an application that requires me to perform speech recognition from a wave file that contains some speech. I know what the words in the wave file could be.So, I need to compare these words from a small custom grammar/dictionalr instead of a whole built in large vocabulary.

I have done the recognition part with the default system large vocabulary but now just need to use my own vocabulary.

Suppose that the words that the user can say are:

hundred degree celcius,

Then, how shall I write my XML Grammar? I suppose that if I use the limited small vocabulary, then my accuracy of recognition would increase. Right now, ive a wave file in Microsoft Mary's voice saying "Hello". But with the large default vocabulary its recognising it as "All though". Is my assumption correct that with the above mentioned 5 words in the vocabulry, it will recognise it as Hello only?

Ive been looking at the internet but can't find solution to my specific problem regarding making a simple grammar. In most documents its mentioning using external grammar and about several of the attributes posssible, including sementics, etc, etc. But my vocabulary is not very complicated or difficult. And I don't want to get into too much detail at the moment as I would be deviating from my project itself..

So using the following code:

Grammar = RecoContext.CreateGrammar

What should be the content of the CustomGrammar.xml?

C# - Getting Started With Speech Recognition Programming?

May 17, 2010

So, you've all probably seen Iron Man where Tony interacts with an AI system called Jarvis. Demo clip here (Sorry it's a commercial).I'm very familiar with C#, C++ and Visual Basic, but I am unsure what options I have available for me to program something like this. Ideally, I'd like to have it assist me while working on some projects by automating a few things.

After doing a bit of research, I saw that a lot of people where using apple script. Well, I'm a windows developer and I work on windows, SO, that won't work.Microsoft has a Speech SDK, but I hear that I can't program it to learn custom words... as in it just uses it's standard library. Is this true? What are the other limitations of speech recognition with the SDK? Is there something else then?

Also, which language would be better to use for a project like this? C# or VB?

Disabling Speech Recognition During TTS Output

May 31, 2011

I've written a "quick and dirty" GUI interface for a CLI chat program, and I've been trying to integrate TTS and Speech Recognition into it, so that the user can "have a conversation" with a chat bot, rather than just "type and read". The TTS portion works well (barring some small pronunciation issues - I have yet to find a TTS voice that can properly pronounce "Geek" without my having to mangle the spelling), and the SR module works well.

If I have the TTS module disabled. The problem I'm having is that the SR module is processing the output from the TTS, and causing issues where an ever-increasing string of TTS output occurs, causing undesirable results. I've tried several methods of temporarily disabling Speech recognition, none of which have proved useful. Below are some short code snippets that I've tried to use:

Imports SpeechLib
Imports System.Drawing
Imports System.Net.Sockets
Public Class Form1
Public voice As New SpVoice

Install Speech Recognition Engine?

I am trying to create a VB.Net form that recognizes speech. When I run it, I get the error "Speech recognition is not available on this system. SAP and Speech Recognition engines cannot be found." So, following Microsoft's instructions, I discover that there is no Speech tab in Speech Properties (which appear when I click on Speech in the control panel). I am using Windows XP Professional. Only a Text-to-Speech tab, no speech recognition tab. To install the speech engine, I went to Add or Remove Programs/ Change Microsoft Office Enterprise 2007/ Add or Remove Features. However there is no "Alternative User Input" as per the instructions. How can I get this speech recognition engine installed?[code]...

Speech Recognition Language - Configuration Not Matching?

I have just bought a new mic. It works just fine with Sound Recorder and MSN Messenger, but not speech recognition. Whenever I try to start Speech Recognition, it says something like "Speech Recognition could not start because the language configuration does not match the one Speech Recognition is using". The language I probably need to use is Microsoft Recognizer v5.1. But whenever I select it, it says that the engine could not be created. I already have my mic configured properly and even the tutorial works perfectly fine and same with the Training the computer thingy.

Windows 7 Speech Recognition As InProc Engine?

Apr 10, 2010

I am currently working with Speech Recognizer 8.0 and trying to develop an application in VB for simple speech recognition tasks. Unfortunately, with Windows 7, anytime speech isenabled, it is listening for any sort of all sorts of commands (ie: "start menu", "press a key", *delete*)... all of which interfere with the desired operation of the program.Now, I believe what my problem is, correct me if I am wrong, is that I should not be using theshared engine, but the "InProc" engine, so the application then has the only access to the speech engine... better question: I know how to add commands to the speech engine, but *how* do I remove all the other commands, so that it only listens for a handful of words/commands that I want it to?

[2005] Speech Object Library - Female Voice?

Feb 17, 2009

I am trying to create a text to speech program that can speak in a female voice and also have the option to save to a WAV file. I have found some code out there using the Microsoft Speech Object Library. but I can only get it to speak using a male voice. Can't seem to find a way to add a female voice. Things I have found says there should be at least a male and a female voice loaded but only the male voice is there. Also, on my PC, i have the SAPI DLL in the C:Program FilesCommon FilesMicrosoft SharedSpeech directory and when i right click and check its properties it says it is version 5.1.4111.0....but when my project is built, the Interop.SpeechLib.dll that is created is version

The code I have is:

Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Voice As SpeechLib.SpVoice


Which speaks fine with the male voice. Haven't attempted the saving to a WAV piece yet since i can't get the female voice.
