Get the Speech SDK for macOS
Important
By downloading any of the Azure Cognitive Services Speech SDKs, you acknowledge its license. For more information, see:
Note that this tutorial will not work with version of the SDK earlier than 1.6.0.
The Cognitive Services Speech SDK for macOS is distributed as a framework bundle.It can be used in Xcode projects as a CocoaPod, or downloaded from https://aka.ms/csspeech/macosbinary and linked manually. This guide uses a CocoaPod.
Create an Xcode project
Start Xcode, and start a new project by clicking File > New > Project.In the template selection dialog, choose the 'Cocoa App' template.
In the dialogs that follow, make the following selections:
- Project Options Dialog
- Enter a name for the quickstart app, for example
helloworld
. - Enter an appropriate organization name and an organization identifier, if you already have an Apple developer account. For testing purposes, you can just pick any name like
testorg
. To sign the app, you need a proper provisioning profile. Refer to the Apple developer site for details. - Make sure Swift is chosen as the language for the project.
- Disable the checkboxes to use storyboards and to create a document-based application. The simple UI for the sample app will be created programmatically.
- Disable all checkboxes for tests and core data.
- Enter a name for the quickstart app, for example
- Select project directory
- Choose a directory to put the project in. This creates a
helloworld
directory in the chosen directory that contains all the files for the Xcode project. - Disable the creation of a Git repo for this example project.
- Choose a directory to put the project in. This creates a
- Set the entitlements for network and microphone access. Click the app name in the first line in the overview on the left to get to the app configuration, and then choose the 'Capabilities' tab.
- Enable the 'App sandbox' setting for the app.
- Enable the checkboxes for 'Outgoing Connections' and 'Microphone' access.
- The app also needs to declare use of the microphone in the
Info.plist
file. Click on the file in the overview, and add the 'Privacy - Microphone Usage Description' key, with a value like 'Microphone is needed for speech recognition'. - Close the Xcode project. You will use a different instance of it later after setting up the CocoaPods.
Add the sample code
- Place a new header file with the name
MicrosoftCognitiveServicesSpeech-Bridging-Header.h
into thehelloworld
directory inside the helloworld project, and paste the following code into it: - Add the relative path
helloworld/MicrosoftCognitiveServicesSpeech-Bridging-Header.h
to the bridging header to the Swift project settings for the helloworld target in the Objective-C Bridging Header field - Replace the contents of the autogenerated
AppDelegate.swift
file by: - In
AppDelegate.swift
, replace the stringYourSubscriptionKey
with your subscription key. - Replace the string
YourServiceRegion
with the region associated with your subscription (for example,westus
for the free trial subscription).
Install the SDK as a CocoaPod
- Install the CocoaPod dependency manager as described in its installation instructions.
- Navigate to the directory of your sample app (
helloworld
). Place a text file with the namePodfile
and the following content in that directory: - Navigate to the
helloworld
directory in a terminal and run the commandpod install
. This will generate ahelloworld.xcworkspace
Xcode workspace containing both the sample app and the Speech SDK as a dependency. This workspace will be used in the following.
Build and run the sample
- Open the
helloworld.xcworkspace
workspace in Xcode. - Make the debug output visible (View > Debug Area > Activate Console).
- Build and run the example code by selecting Product > Run from the menu or clicking the Play button.
- After you click the 'Recognize' button in the app and say a few words, you should see the text you have spoken in the lower part of the app window.
Next steps
macOS Catalina introduces Voice Control, a new way to fully control your Mac entirely with your voice. Voice Control uses the Siri speech-recognition engine to improve on the Enhanced Dictation feature available in earlier versions of macOS.1
How to turn on Voice Control
After upgrading to macOS Catalina, follow these steps to turn on Voice Control:
- Choose Apple menu > System Preferences, then click Accessibility.
- Click Voice Control in the sidebar.
- Select Enable Voice Control. When you turn on Voice Control for the first time, your Mac completes a one-time download from Apple.2
Voice Control preferences
When Voice Control is enabled, you see an onscreen microphone representing the mic selected in Voice Control preferences.
To pause Voice Control and stop it from from listening, say 'Go to sleep' or click Sleep. To resume Voice Control, say or click 'Wake up'.
How to use Voice Control
Get to know Voice Control by reviewing the list of voice commands available to you: say 'Show commands' or 'Show me what I can say'. The list varies based on context, and you may discover variations not listed. To make it easier to know whether Voice Control heard your phrase as a command, you can select 'Play sound when command is recognised' in Voice Control preferences.
Basic navigation
Voice Control recognises the names of many apps, labels, controls and other onscreen items, so you can navigate by combining those names with certain commands. Here are some examples:
- Open Pages: 'Open Pages'. Then create a new document: 'Click New Document'. Then choose one of the letter templates: 'Click Letter. Click Classic Letter'. Then save your document: 'Save document'.
- Start a new message in Mail: 'Click New Message'. Then address it: 'John Appleseed'.
- Turn on Dark Mode: 'Open System Preferences. Click General. Click Dark'. Then quit System Preferences: 'Quit System Preferences' or 'Close window'.
- Restart your Mac: 'Click Apple menu. Click Restart' (or use the number overlay and say 'Click 8').
You can also create your own voice commands.
Number overlays
Use number overlays to quickly interact with parts of the screen that Voice Control recognises as clickable, such as menus, checkboxes and buttons. To turn on number overlays, say 'Show numbers'. Then just say a number to click it.
Number overlays make it easy to interact with complex interfaces, such as web pages. For example, in your web browser you could say 'Search for Apple stores near me'. Then use the number overlay to choose one of the results: 'Show numbers. Click 64'. (If the name of the link is unique, you might also be able to click it without overlays by saying 'Click' and the name of the link.)
Mac Os X Free Software
Voice Control automatically shows numbers in menus and wherever you need to distinguish between items that have the same name.
Grid overlays
Use grid overlays to interact with parts of the screen that don't have a control, or that Voice Control doesn't recognise as clickable.
Say 'Show grid' to show a numbered grid on your screen, or 'Show window grid' to limit the grid to the active window. Say a grid number to subdivide that area of the grid, and repeat as needed to continue refining your selection.
To click the item behind a grid number, say 'Click' and the number. Or say 'Zoom' and the number to zoom in on that area of the grid, then automatically hide the grid. You can also use grid numbers to drag a selected item from one area of the grid to another: 'Drag 3 to 14'.
To hide grid numbers, say 'Hide numbers'. To hide both numbers and grid, say 'Hide grid'.
Dictation
When the cursor is in a document, email message, text message or other text field, you can dictate continuously. Dictation converts your spoken words into text.
- To enter a punctuation mark, symbol or emoji, just speak its name, such as 'question mark' or 'per cent sign' or 'happy emoji'. These may vary by language or dialect.
- To move around and select text, you can use commands such as 'Move up two sentences' or 'Move forward one paragraph' or 'Select previous word' or 'Select next paragraph'.
- To format text, try 'Bold that' or 'Capitalise that', for example. Say 'numeral' to format your next phrase as a number.
- To delete text, you can choose from many delete commands. For example, say 'delete that' and Voice Control knows to delete what you just typed. Or say 'Delete all' to delete everything and start over.
Voice Control understands contextual cues, so you can seamlessly transition between text dictation and commands. For example, to dictate and then send a birthday greeting in Messages, you could say 'Happy Birthday. Click Send.' Or to replace a phrase, say 'Replace I’m almost there with I just arrived'.
You can also create your own vocabulary for use with dictation.
Create your own voice commands and vocabulary
Create your own voice commands
- Open Voice Control preferences, such as by saying 'Open Voice Control preferences'.
- Click Commands or say 'Click Commands'. The complete list of all commands opens.
- To add a new command, click the add button (+) or say 'Click add'. Then configure these options to define the command:
- When I say: Enter the word or phrase that you want to be able to speak to perform the action.
- While using: Choose whether your Mac performs the action only when you're using a particular app.
- Perform: Choose the action to perform. You can open a Finder item, open a URL, paste text, paste data from the clipboard, press a keyboard shortcut, select a menu item or run an Automator workflow.
- Use the checkboxes to turn commands on or off. You can also select a command to find out whether other phrases work with that command. For example, 'Undo that' works with several phrases, including 'Undo this' and 'Scratch that'.
Speech Recognition Free App Mac Os X
To quickly add a new command, you can say 'Make this speakable'. Voice Control will help you configure the new command based on the context. For example, if you speak this command while a menu item is selected, Voice Control helps you make a command for choosing that menu item.
