Examples

With SINGLE VoiceId

// Returns the array with the voice(s) data.
// Depending on the selected language this array can have more than one element.

  LanguageName: 'Brazilian Portuguese',
  Id: 'Vitoria',
  LanguageCode: 'pt-BR'
 }]
 */

// Get the VoiceId.
// If there is only one element in voiceData array then it will return that voiceId.
// Otherwise it will return a random voiceId based on the criteria (chained methods and/or filters).
// See the next example for clarity.
const voiceId = brazilianFemaleVoice.id // Vitoria

With MULTIPLE VoiceId

const Voices = require('aws-polly-voices')
const voices = new Voices()
