Speech Recognition API (1)

Let’s try voice recognition by using “Speech Recognition API” which is released in iOS 10.0.

Basically, I’ll explain the following official sample program.

SpeakToMe: Using Speech Recognition with AVAudioEngine

Environment

• macOS Sierra 10.12.1
• Xcode 8.1
• iOS 10.1.1

Step 1

At first, create a new project in Xcode.

Step 2

Next, move to the project top, and execute pod init.

At this time, I don’t have a plan to use other libraries, so this step is not required.

Then, let’s open the directory whose extension is xcworkspace.

Step 3

From iOS 10, we have to write purposes to use features related to privacy access in Info.plist. Otherwise, the app is terminated forcibly.

Edit Info.plist as below.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>NSSpeechRecognitionUsageDescription</key>
	<string>sample description</string>
	<key>NSMicrophoneUsageDescription</key>
	<string>sample description</string>

	<!-- ... -->

</dict>
</plist>

Step 4

Open ViewController.swift, and import the speech library.

import Speech

I’ll write a coding part in next article, because it’ll be too long.

Look forward to it!
