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

"No more slot" error message

When I use Long sentence recognition>Live streaming recognition (gRPC), the "No more slot" error message is displayed.

Cause

This error may occur temporarily when the call volume is concentrated at that time.
When the access error occurs intermittently in the streaming recognition service, this error may occur.

Solution

As this error message is displayed when the call volume is concentrated temporarily, try to call again after a certain time.

"ERROR_INVALID_SECRET" error message

"ERROR_INVALID_SECRET" error message is displayed.

Cause

This error may occur when the Secret Key value was entered incorrectly.

Solution

• Check if the Secret Key is correct.
  • To check the Secret Key, see Long sentence recognition builder > Check API call information.
• Check if the Invoke URL is correct.
  • If you drag and copy the Invoke URL, the value may be missing. Click the [Copy] button to copy the value.

"RESOURCE_EXHAUSTED" error message

• "RESOURCE_EXHAUSTED:Too many channels, the max channel is: 15" error message is displayed.
• Even if it just maintains the single streaming connections, the "RESOURCE_EXHAUSTED" error occurs.
• "No more available resources for connecting gRPC" error message is displayed.

Cause

The number of simultaneous connections to gRPC is limited to 15 per domain. When the number of connections exceeds 15, this error may occur.

Solution

• Once the voice recognition ends, end the gRPC connections.
  • To end channels, use common development codes, such as channel.shutdown and channel.close. For detailed examples, see the content for live streaming recognition.
  • Maintain the channel connections in the unit of single streams where voice recognition requests continue.
    Example: in the case of live broadcasting, end the gRPC connections at the time the live broadcasting ends.
• It is recommended to apply the timeout logic depending on the transfer/receipt of voice recognition data.
  • If you continue to maintain the connections while there is no transfer/receipt, a problem occurs in obtaining gRPC channels.

"ERROR_REQUEST_PARAMETER" error message

"ERROR_REQUEST_PARAMETER" error message is displayed.
"Speaker detect is off" error message is displayed.

Cause

The diarization.enable value is entered incorrectly. diarization.enable is used as follows:
"diarization" : { "enable" : false }

Solution

When you do not enter diarization.enable value, true is applied by default. When you set the speaker detect status to "Off", set the diarization.enable value to "false", then call. For more information, see Long sentence recognition builder.
