At one point I was going to look at trying to port this library to the iPhone:

How to recognize the human voice by code in 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.

Adding recorded voice recognition iPhone

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 need to now the accuracy of OpenEars, speech library for IPhone using CMUSphinx?

hello
any one who have used this OpenEars, speech library for IPhone using CMUSphinx and can tell me how much it is helpful for speech to text conversion for iOS and with how much accuracy i need to attain 80% speech should be converted to text is this library can do this for me
help required
thanx in advance.
OperEars API has its internal word storage that make it very reliable in terms of accuracy you can increase the accuracy with passage of time by adding user defined word with user's own speech that is a big feature of this API see this

Convert the voice to text in 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

How to convert speech to text in iphone?

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 Nuanceā€™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.
