How to Use Speech Recognition Inside the iOS Sdk

How to use Speech Recognition inside the iOS SDK?

There are many libraries availble. You can use any of them.

1. openears // This is the best library

2. VocalKit (Deprecated for open ears)

3. TTS
4. ispeech (Not free)

Hope it helps you.

NOTE:

if you download openears (which contains a sample project called "OpenEarsSampleApp") @efimovD mentions this

Check the code in view controller and you will see an array with
possible commands. This thing detects commands! Not some talk. It
listens and tries to compare what you've said with the words from
array

How to use Offline Speech Recognition inside the iOS SDK?

There are many, here are the SDK's that I have used earlier (both are free and offline)

1. Openears

2. Flite

iPhone: Speech Recognition is in IOS SDK available?

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.

Is there a way to use iOS speech recognition in offline mode?

I am afraid that there is no way to do it (however, please make sure to check the update at the end of the answer).

As mentioned at the Speech Framework Official Documentation:

Best Practices for a Great User Experience:

Be prepared to handle the failures that can be caused by reaching speech recognition limits.
Because speech recognition is a network-based service, limits are
enforced so that the service can remain freely available to all apps.

As an end user perspective, trying to get Siri's help without connecting to a network should displays a screen similar to:

Also, When trying to send a massage -for example-, you'll notice that the mike button should be disabled if the device is unconnected to a network.

Natively, the iOS itself won't able this feature until checking network connection, I assume that would be the same for the third-party developer when using the Speech Framework.

UPDATE:

After watching Speech Recognition API Session (especially, the part 03:00 - 03:25) , I came up with:

Speech Recognition API usually requires an internet connection, but there are some of new devices do support this feature all the time; You might want to check whether the given language is available or not.

Adapted from SFSpeech​Recognizer Documentation:

Note that a supported speech recognizer is not the same as an
available speech recognizer; for example, the recognizers for some
locales may require an Internet connection. You can use the
supported​Locales() method to get a list of supported locales and the
is​Available property to find out if the recognizer for a specific
locale is available.

iPhone speech recognition API?

The SDK does not support either voice recognition or text to speech. Voice recognition is only available through the Voice control app, and text to speech is only available through the accessibility APIs when accessibility is turned on.

As for speed, it should be fast, you probably don't use it properly. As I understood you have text already and you need to build grammar from this text.
