The command you provided appears to be using the "tts" function or script with the option "--model_info_by_idx".

Here's a breakdown of the command and its components:

• "tts": It suggests that this command is related to a text-to-speech (TTS) functionality or tool.
• "--model_info_by_idx": It is an option or argument that specifies the command to provide information about a TTS model based on its index (idx).
• "${model_type-model_query_idx}": This part utilizes a variable substitution syntax to pass values dynamically. It suggests that the variable "model_type" and "model_query_idx" should be defined elsewhere, and their values will be inserted in place. The actual values of "model_type" and "model_query_idx" will determine which TTS model information is fetched.

In summary, this command seems to be calling a TTS tool or script and requesting information about a specific TTS model by its index, with the actual model index determined by the values assigned to the variables "model_type" and "model_query_idx".
