  writer.pipe(stream)
}
convertTextToSpeech('Hello, world!');

async function textToSpeech(text: string) {
  const voiceId = 'voice-id'; // Replace with a valid voice ID
  const response: Buffer = await elevenLabsAPI.textToSpeech(voiceId, {text: text});
  // Handle the stream, e.g., save to a file or play audio
