# CLOVA Voice troubleshooting

Available in Classic and VPC

You might run into the following problems when using CLOVA Voice. Find out causes and possible solutions.

## Downloading and reusing voice files

Unable to use CLOVA Voice on internal or closed networks. I want to download voice files and play them on my own server.

#### Cause

CLOVA Voice is provided as an API and can only be used in environments where the API can be called in real-time. Reusing data obtained after an API request is not allowed.

#### Solution

As CLOVA Voice requires real-time API calls, you cannot insert voice files into software or hardware, or use it on internal or closed networks. For use in private environments, set up a separate host that can communicate externally. Alternatively, use [CLOVA Dubbing service](https://www.ncloud.com/product/aiService/clovaDubbing) which allows you to download voice files.

## Delay function for specific sections

Unable to set pause time between sentences. I want to temporarily pause a specific section.

#### Cause and Solution

No function is provided to delay specific sections. Adjustments can be made using commas and periods, but only within 0.5 to 1 second.

## API call errors

API call results in an error.

#### Cause

- Incorrectly entered API URL during the call.
- Exceeded the allowed character count.
- Unsupported function.

#### Solution

- Check the API URL used for the call. The API URL for the private platform is `https://naveropenapi.apigw.ntruss.com/tts-premium/v1/tts`.
- Up to 2000 characters can be requested per API call. Adjust your request to within 2000 characters.
- For a detailed description of errors that may occur during API calls, see [CLOVA Voice API guide](https://api.ncloud-docs.com/docs/en/ai-naver-clovavoice-ttspremium#%EC%98%A4%EB%A5%98-%EC%BD%94%EB%93%9C).
