Describe the bug

Voice on realtime Agent not changing doesn't matter which configs I pass, by looking at the typescript types I see that there's a deprecated config and a newly created type definition. Which one should I use, the new one still not well supported?

Debug information

• Agents SDK version: (e.g. v0.3.0)
• Runtime environment (e.g. Node.js 20.9.0)

Repro steps

      this.agent = new RealtimeAgent<RealtimeContextData<VoiceAgentContext>>({
        name: `triage_agent`,
        instructions: agentInstructions,
        tools,
      });

      const session = new RealtimeSession<
        RealtimeContextData<VoiceAgentContext>
      >(this.agent, {
        model: 'gpt-realtime',

        config: {
          // Tried here 
          voice: 'marin',

          // Turn detection must also be top level
          turnDetection: {
            type: 'server_vad',
            threshold: 0.5,
            prefix_padding_ms: 300,
            silence_duration_ms: 500,
          },

          // Tried to change voice on audio as well
          //
          audio: {
            input: {
              transcription: {
                model: 'whisper-1',
                language: 'en',
              },
            },
            output: {
              format: 'pcm16',
            },
          },
        },

        context: {
          ...agentContext,
          history: [],
        },
      });

Expected behavior

I would expect to the Agent to take the voice that I'm passing to.

Thanks for reporting this. The top-level voice is kept for backward-compatibility, but it seems it's not functional as expected. I will improve it shortly, but for now, using config.audio.output.voice instead should work for you.
