Whisper API call with async/await

Hi ,
by calling the api this way
await client.audio.speech.create(
model=“tts-1”,
voice=“shimmer”, # os.getenv(“OPENAI_VOICE_NAME”, “Shimmer”),
input=text,
response_format=“wav”,
)
I am getting this error “Error: object HttpxBinaryResponseContent can’t be used in ‘await’ expression”.
What is the proper way to call in a async ?
