Is there a LanguageCode import?

Thanks for reaching out, Andrii. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

Is

language

required in

SpeechData

object initialization?

Which SDK/language are you using (Python, Node.js, or other)? Could you paste the

SpeechData

initialization code you're using or the package/version so I can confirm whether

language

is required? , with interactive elements

Python

Thanks — regarding whether

language

is required in

SpeechData

for Python: • No, you do not need to set

language

when initializing

SpeechData

. •

language

is populated by STT providers when they return language-detection results (e.g., Deepgram with

detect_language=True

, Soniox with

enable_language_identification=True

). It’s a read-only output, not an input you must provide. If you want, tell me which STT provider and example code you’re using and I can show how to enable language detection and where the detected

language

appears in the

SpeechEvent

output.

Thanks — you're right to call this out. Short answer: the Python

SpeechData

class requires a

language

positional argument when you instantiate it. Even though STT providers populate

language

for events, if you create a

SpeechData

instance yourself you must pass

language

. What you can do: • Import

LanguageCode

and pass a value when constructing:

from livekit.agents import LanguageCode

sd = SpeechData(
    LanguageCode("en-US"),
    text="hello",
    start_time=0.0,
    end_time=1.0,
)

• If you don't know the language (e.g., you want a placeholder until detection runs), pass a sensible default like

"und"

or

"en-US"

depending on your flow:

sd = SpeechData(LanguageCode("und"), text="...", ...)

If you share the code where you create

SpeechData

, I can suggest the exact minimal change to satisfy Pylance/mypy. , with interactive elements
