Adobe has announced that it will acquire collaborative design platform Figma for nearly $20 billion.

Dylan Field and Evan Wallace started working on Figma in 2012. Today, the app is popular with designers and developers and can be considered a competitor to Adobe XD which is a similar design tool for web and mobile apps.

Adobe believes that the combination of Adobe and Figma will push to a new era of co-creation.

The transaction is expected to close in 2023. Dylan Field will then continue to lead the Figma team, reporting to David Wadwani, President of Digital Media Business at Adobe.

最近Flutterで仕事をすることになり
勉強したこと、調査されたことを共有したいと思います。

Flutterでテキストを音声に変換したりプログラムです。
さまざまな言語、音量、ピッチ、スピードなどを設定することができます。

今の例では、言語を英語に設定していますが、もし日本語にしたい場合は、以下のように設定することができます。

flutterTts.setLanguage("ja-JP")

利用するためには、まず pubspec.yaml ファイルにflutter_tts、このパッケージを追加する必要があります。

後、AndroidManifest.xmlファイルのqueries要素にTextToSpeech.Engine.INTENT_ACTION_TTS_SERVICEを追加する必要があります。

<queries>
   <intent>
       <action android:name="android.intent.action.TTS_SERVICE" />
   </intent>
</queries>
   <application

以下のパスを目的のファイルでインポートします。

import 'package:flutter_tts/flutter_tts.dart';

利用するには

FlutterTts ftts = FlutterTts();

再生するテキストを追加した後、テキストを音声に変換することができます。

var result = await ftts.speak("Hello there!");

言語、音声の大きさ、話すスピード、ツールのピッチなどを設定するには、以下の方法で出来ます。

await ftts.setLanguage("en-US");
await ftts.setSpeechRate(1.0); 
await ftts.setVolume(0.5); 
await ftts.setPitch(1);

以上だけです。

テストプログラムではボタンをタップした後、上記のプログラムを行うようにしています。

ElevatedButton(
  onPressed:() async {
        //
        ...
       //                  
     }, 
 child: Text("Text to Speech"))

ということで、今回はこれで終わります。
