[05/29/2024 04:10:56 PM China Standard Time] Failed to submit batch synthesis job: {
"code": "Forbidden",
Only \"Standard\" subscriptions for the region of the called service are valid.
}

ERROR: An expected file was not found. This is likely because the TTS service failed to synthesize the audio. Refer to any error messages above.
