Bug: Qwen ASR API 400 - 'voice' property is required when using voice-to-text

Description

Voice-to-text transcription fails when calling the Qwen ASR API, returning a 400 error with the message "The voice property is required."

Error

qwen asr API 400: {"error":{"message":"The voice property is required.","type":"invalid_request_error","param":null,"code":"invalid_parameter_error"},"id":"chatcmpl-9fe00cf4-3057-9504-a1f9-b9d7ec22ee0b","request_id":"9fe00cf4-3057-9504-a1f9-b9d7ec22ee0b"}

Expected Behavior

Voice-to-text should successfully transcribe audio to text.

Actual Behavior

Qwen ASR API returns HTTP 400 because the voice parameter is missing from the request body.

Environment

• opencode version: 1.18.7
• OS: Windows
• API provider: Qwen

Additional Context

The voice parameter is required by Qwen's ASR API to specify the speaker voice type. The opencode client is not including this parameter when making the ASR request.
