_speak = () => {
    const start = () => {
      this.setState({ inProgress: true });
    };
    const complete = () => {
      this.state.inProgress &&
        this.setState({ inProgress: false, paused: false });
    };

    Speech.speak(this.state.selectedExample.text, {
      voice: this.state.voice,
