QHSpeechSynthesizerQueue

Queue management system for AVSpeechSynthesizer

Installation

Cocoapods

Add this to your Podfile:

pod 'QHSpeechSynthesizerQueue'

Run a pod install and import the header where you need it:

#import <QHSpeechSynthesizerQueue.h>

Manually

Drop QHSpeechSynthesizerQueue.h and QHSpeechSynthesizerQueue.m in your project, then

#import "QHSpeechSynthesizerQueue.h"

Usage

Initialization

QHSpeechSynthesizerQueue *synthesizerQueue = [[QHSpeechSynthesizerQueue alloc] init];

Adding messages to the queue

Add a message at the end of the queue

[synthesizerQueue readLast:@"This message will be added to the end of the queue" 
                  withLanguage:@"en_US"
                  andRate:@"0.2"];

Insert a message to be read immediatly after the current message being read

[synthesizerQueue readNext:@"This message will be read next"
                  withLanguage:@"en_US"
                  andRate:@"0.2"
                  andClearQueue:NO];

If you set andClearQueue: to YES, the queue will be cleared and this will be the last message to be read.

Interrupt the current message and read this one immediately

[synthesizerQueue readImmediately:@"This message will be read next"
                  withLanguage:@"en_US"
                  andRate:@"0.2"
                  andClearQueue:NO];

If you set andClearQueue: to YES, the queue will be cleared and this will be the last message to be read.

Playback actions

Stop

Stop the queue's playback and clear the queue immediately.

[synthesizerQueue stop];

Stop after current

Stop the queue's playback and clear the queue. If something is currently being read, it will stop afterwards.

[synthesizerQueue stopAfterCurrent];

Pause

Pause the queue's playback immediately.

[synthesizerQueue pause];

Pause after current

Pause the queue's playback. If something is currently being read, it will pause afterwards.

[synthesizerQueue pauseAfterCurrent];

Resume

[synthesizerQueue resume];

Clear queue

[synthesizerQueue clearQueue];

Properties

BOOL duckOthers

Set this to YES to duck all the device's audio sessions when a string is being read. Defaults to YES.

synthesizerQueue.duckOthers = YES;

NSTimeInterval preDelay

The delay before reading a message. Default is 0.0

synthesizerQueue.preDelay = 1.0;

NSTimeInterval postDelay

The delay after reading a message. Default is 0.0

synthesizerQueue.postDelay = 1.0;

Delegate

You can set a QHSpeechSynthesizerQueueDelegate to be notified of playback events.

@protocol QHSpeechSynthesizerQueueDelegate <NSObject>

@optional
- (void)speechSynthesizerQueueDidStartTalking:(QHSpeechSynthesizerQueue *)queue;
- (void)speechSynthesizerQueueDidFinishTalking:(QHSpeechSynthesizerQueue *)queue;
- (void)speechSynthesizerQueueDidPauseTalking:(QHSpeechSynthesizerQueue *)queue;
- (void)speechSynthesizerQueueDidContinueTalking:(QHSpeechSynthesizerQueue *)queue;
- (void)speechSynthesizerQueueDidCancelTalking:(QHSpeechSynthesizerQueue *)queue;
- (void)speechSynthesizerQueueWillStartTalking:(QHSpeechSynthesizerQueue *)queue;
