如何将拉丁西班牙语设置为Google cloud文本到语音的语音转换？

from google.cloud import texttospeech

def synthesize_text(text, output_file):
    client = texttospeech.TextToSpeechClient()

    synthesis_input = texttospeech.SynthesisInput(text=text)

    voice = texttospeech.VoiceSelectionParams(
        language_code="es-ES", # 设置为拉丁西班牙语
        ssml_gender=texttospeech.SsmlVoiceGender.FEMALE # 设置声音性别，可选
    )

    audio_config = texttospeech.AudioConfig(
        audio_encoding=texttospeech.AudioEncoding.MP3 # 设置音频编码格式，可选
    )

    response = client.synthesize_speech(
        input=synthesis_input, voice=voice, audio_config=audio_config
    )

    with open(output_file, "wb") as out:
        out.write(response.audio_content)
        print(f'音频文件已保存至 {output_file}')

# 调用示例
synthesize_text("Hola, ¿cómo estás?", "output.mp3")
