## Quando quer uma voz mais natural

As vozes integradas são claras, mas cansam em textos longos. As apps de leitura acrescentam vozes neurais: Speechify, ElevenReader e NaturalReader na nuvem, ou o SpeechBee, que nós fazemos, no seu Mac. Selecione texto em qualquer app do Mac, prima a sua tecla de leitura e uma voz natural lê-o sem que o texto saia do Mac.
