In my program I have some recorded voice. After that I need to recognition it, for example: I launched program, saying something, and when program received word that have been recorded it shows UIAlertView. Anybody knows any sdk or example code? Thanks..
Hope the below link will helpful for you. They will also provide sample app for recognizing sounds. Download it and try it.
Ispeech SDK
Please note that ispeech does not perform natural voice recognition and the advertising materials are very misleading. The voice recognition piece of iSpeech requires a set vocabulary similar to the open source (and free) OpenEars SDK.
Nuance recently updated their developer program to give mobile developers limited free access to their speech recognition servers. Look at http://dragonmobile.nuancemobiledeveloper.com/public/index.php
If you don't want to use network to transfer audio, try OpenEars, the library for embedded speech recognition on IPhone

I want to integrate voice detection in my iPhone app. The iPhone app allow the user to search the word by using their voice. But, i don't know a single info about Voice Recognition in iPhone. Can you please suggest me any ideas,tutorials or sample code for this?
You can also use Google Chrome API to integrate voice recognition on your application, but there is a big problem : the API works only with FLAC encoded files, but this encoding isn't supported natively on iOS... :/
You can see those 2 links for more information :

EDIT :
I realized an application including voice recognition using Nuance SDK, but it's not free to use. You can register for free and get a developer key that allows you to test your application for 90-days. An application example is included, you can see the code, it's very easy to implement.
Good luck :)
The best approach will probably be to:
Record the voice on the phone
Send the recording to a server that runs the speech recognition software
Then return something to the phone to indicate what it should do
This approach is favorable as there are a number of open source voice to text softwares out there & you are not limited by computing power in the backend.
Having said that, iOS has OpenEars which is based on Pocket Sphinx. It looks promising...
Well voice recognition is not correlated with iphone. All you can do is record the voice in iphone. Once done, you can either code your one voice recognition module, or find a third party API and reuse it.
You can do google search on that.
I am working on a project where I have to record a voice covert into text then match the pattern and according to the user command perform action.
I am able to to record voice of the user through AVAudioRecorder and perform action. But the actions are perform on anything what user says. I want to perform on user's particular word like if he say play then playing should start.
Help me by any tutorial or any sample code.
Thanks in Advance
Most apps (including Siri) send the sound file to a remote data center via to do the speech recognition, which involves some fairly heavy duty processing. Nuance may have an commercial API.
Another option might be to try using the CMU OpenEars or PocketSphinx speech library, which has been ported to the iPhone. Also look at VocalKit and this article on running PocketSphinx on the iPhone.
Does anyone knows that if "speech to text" and "text to speech" api's used in Siri are accessible in IOS 5 or IOS 6 SDK?
I researched but couldn't find anything about it in documentation, so if thats not included in SDK are there any "Siri" quality libraries in market?
Siri is not available in API form yet, however, any UITextField or UITextArea can be dictated to using the built-in option for speech-to-text.
Check out Openears at: http://www.politepix.com/openears I've used it experimentally and it worked great. It will recognize preset vocabularies very well. There is a slight pause of 1/2 second or so before it recognizes the word and it gets confused in an environment with a lot of voices (a crowded restaurant), but in a reasonably quiet setting I found it works great.
iOS 10 introduces a new speech recognition API - SFSpeechRecognizer.
https://developer.apple.com/videos/play/wwdc2016/509/
Siri is only available as a beta on iPhone 4S, not sure if the plan is to spread it to all iOS 5 capable devices. Open source libraries for voice recognition are hard to come by. You could look into Nuance (dragon) developer gateway here.
You might also want to check out ispeech's text to speech and speech recognition APIs. They already allow you to include it in your apps without much trouble and actually are a bit better than what Siri has. Siri's big strength is the NLP, not so much the underlying speech tech.
After iOS 10 you can use
Speech.framework
It is very simple to use.Just import Speech into your class
import Speech
let speechRecogizer = SFSpeechRecognizer(locale: Locale.init(identifier: "en-US"))! //locale whatever you want to use
let recognitionRequest = SFSpeechAudioBufferRecognitionRequest()
let recognitionTask:SFSpeechRecognitionTask = speechRecogizer.recognitionTask(with: recognitionRequest, resultHandler: { (result, error) in
print(result?.bestTranscription.formattedString) //here you can get your text
})
You can also check https://github.com/PKrupa94/SpeechManager for it.
Siri is not available to Developers yet.
We've made an SDK for isolated words (or small phrases) recognition, CeedVocal SDK. We use it in our own app Vocalia. It's not free though (but there's free trial), more information at: http://www.creaceed.com/ceedvocal
For speech recognition you can use OpenEars (http://www.politepix.com/openears/) which works offline and provide good accuracy.OpenEars is free to use in an iPhone or iPad app.
Yes OpenEars handles Speech to Text function.
I need to synthesize a voice so that it can be used to speak the text that is supplied to it. how can it be done in iPhone. I went through Sphinx voice synthesizer and other voice synthesizers, but they have some predefined voice for converting text to speech. In my app I require the voice provided by me to respond back.
Any suggestions in this regarding where to start with, is very helpful.
Thanks in advance.
I am looking for the same thing. It looks that apple doesn't provide any library for that, despite the fact the iPhone uses for speech during auto-text. The only way I have found till now is using 3rd party http://www.ispeech.org/developers/iphone. I havent tested yet.
I want to build an application where user when talks something on iphone it will convert into corresponding text.
I heard in windows platform it is possible.
Wheather this is possible in iphone ? Any API available for this ?
I used Nuance’s Dragon Speech SDK for this purpose.
Its free for developers and their SDK have a sample project for STT and TTS both.
Tried Speech to text using this SDK on iOS 9 and it works like a charm.
Here is the link.
https://developer.nuance.com/public/Help/DragonMobileSDKReference_iOS/SpeechKit_Guide/RecognizingSpeech.html
Limitations:
60 seconds recording time limit.
Recorded audio file is not accessible.
Pauses taken are detected as end of recording.
There's an app for that.
Search for "Dragon Speech".
The question has been asked a lot of times here already, this being one of these questions that received quite a few answers and good ideas.
There is no API for doing speech to text on the iPhone, but you can record the voice on the phone, send the recording to a server that runs the speech recognition software on Windows or whatever OS suits you best, then return the text results back to the phone.
It is possible on the iPhone. Pocketsphinx has been ported. For example, an app called cactus dialer uses pocketsphinx. No API has been published but its not hard to get it built. Many people have.
For full blown dictation it will be hard. You will need to make it server based like Nuance's 'dragon speech' does or accept a smaller vocabulary.
