bug: Delay before Utterance when calling speak() Method

[ThomasWagner-dev]

Plugin version: 2.0.1

Platform(s): Web, Android?, Ios?

Current behavior:
When supplying "lang" and "rate" arguments to the "speak()" Method there is a long delay before the utterance starts. This does not happen, when not suppling "lang" or "rate" arguments.

Expected behavior:
No delay before the utterance when calling "speak()", regardless of arguments given.

Steps to reproduce:

• Install Plugin
• Create "TTSOptions" Array with "lang" or "rate" specified
• Call "speak()" Method with those Options

Related code:

// Type definitions of variables used, values are assigned before initialising the "options" Array.
public playBackSpeed: number;
let filteredText: string;

// Initialise variables...

const options: TTSOptions = {
        text: filteredText,
        lang: 'de-DE',
        rate: this.playBackSpeed,
        pitch: this.pitch,
        volume: 1.0,
        category: 'ambient'
      };
      try {
        await TextToSpeech.speak(options);
        this.speaking = false;
      } catch (e) {}
