I am using the gemini-live-2.5-flash-native-audio with my Google Agent development kit agent. Suddenly, it started generating input transcripts in Hindi, Chinese, and other random languages, even though I had explicitly instructed it in the prompt to use english. I tried disabling VAD and using ActivityStart and ActivityEnd instead, but the issue remains the same.
run_config = RunConfig(
streaming_mode=StreamingMode.BIDI,
response_modalities=["AUDIO"], # Required for your PCM player
input_audio_transcription=types.AudioTranscriptionConfig(),
output_audio_transcription=types.AudioTranscriptionConfig(),
session_resumption=types.SessionResumptionConfig(),
context_window_compression=types.ContextWindowCompressionConfig(
trigger_tokens=100000, # Start compression at ~78% of 128k context
sliding_window=types.SlidingWindow(
target_tokens=80000 # Compress to ~62% of context, preserving recent turns
)
),
proactivity=types.ProactivityConfig(proactive_audio=True) if proactivity else None,
enable_affective_dialog=affective_dialog,
speech_config=types.SpeechConfig(
voice_config=types.VoiceConfig(
prebuilt_voice_config=types.PrebuiltVoiceConfig(
voice_name=os.getenv("AGENT_VOICE", "Puck")
)
),
language_code=os.getenv("AGENT_LANGUAGE", "en-US")
)
Any idea, how can this be fixed.
