Is there a way to sequence nativescript text-to-speech messages and use a callback function?
How can the finished callback function be utilized?
The SpeakOptions in nativescript-texttospeech include a finishedCallback property.
I want the TTS to read texts sequentially, that's all.
talk("First message");
talk("Second message");
talk("Last message");

import { TNSTextToSpeech, SpeakOptions as speakoptions } from "nativescript-texttospeech";
let TTS = new TNSTextToSpeech();
export default {
data() {
return {
speakoptions: {
text: " ",
locale: "en-GB",
finishedCallback: "" // what kind of function it should be?
}
};
},
methods: {
start: async function() {
await this.talk("First message");
await this.talk("Second message");
await this.talk("Last message");
},
talk: function(message) {
this.speakoptions.text = message;
return TTS.speak(this.speakoptions);
}
}
};
