I am going to design an App for iPhone 4s where user will have Speech to text feature.
When user taps on UITextView, keyboard will open with microphone option on the left of SpaceKey.
Now my question is, Can I use that microphone option as text input for textview using speech.
I dont have iPhone 4s yet, that why, I can not test it own.
As far as I know, there is no SIRI API available to developers yet (though there are quite a few asking for it).
Speech to text (i.e. the microphone next to the space bar) is a system-level keyboard feature. Any text field that uses the standard keyboard can use speech to text.
You may use the OpenEars for such purpose.
OpenEars is an open-source iOS library for implementing round-trip English language speech recognition and text-to-speech on the iPhone and iPad.
take a look of this link.
Has good discussion regarding this topic

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.
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.
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 ask a question about the iPhone application. Does Apple provide any API to the developers to record the phone call and convert it to text message? Thank you.
In short, there are no APIs for recording phone calls or converting text to speech. You will need to create a speech recognition engine. I suspect the iPhone hardware will not be powerful enough to handle that type of processing though.
FYI...
APIs for converting Voice/Audio data in to text
API for Voice recognition in among group
iPhone speech recognition API?
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.
