List-valued settings like keyterm, keywords, search, redact, and replace
were being converted to strings before being passed to the SDK connect()
method. The SDK expects lists so its encode_query can produce repeated
query params (keyterm=a&keyterm=b).
Raw strings like "de-DE" passed as the language parameter to TTS/STT services
were bypassing the Language enum resolution logic, causing silent failures
(e.g. ElevenLabs expects "de" not "de-DE"). Now raw strings are first converted
to Language enums so they go through the same resolve_language() path, with a
warning logged for unrecognized strings.
Reset stop strategies at turn start (not just turn stop) so that late
transcriptions arriving between turns do not leave stale _text that
causes premature stops on the next turn. Also cancel pending timeout
tasks in reset() for both SpeechTimeout and TurnAnalyzer strategies.
Expose enable_dialout as a configure() parameter (default False) so
dial-out examples can opt in without needing to build DailyRoomProperties
manually.
Narrow misleading Optional type hints on parameters that never accept
None, extract the duplicated token_exp_duration * 60 * 60 calculation,
remove unnecessary forward-reference quotes on DailyMeetingTokenProperties,
and clarify why enable_dialout is explicitly set to False.
Handle Daily's on_dtmf_event callback, convert it to an
InputDTMFFrame pushed into the input transport. Also add __str__
methods to InputDTMFFrame and OutputDTMFFrame for better logging.
Refactor language_to_soniox_language to use resolve_language + LANGUAGE_MAP
pattern consistent with other services. Fix resolve_language fallback to use
str(language) instead of language.value so plain strings don't crash.
The base_url parameter previously forced wss:// and https:// schemes,
breaking air-gapped or private deployments that need ws:// or http://.
Extract URL derivation into _derive_deepgram_urls() helper that respects
the developers scheme choice while deriving the paired WebSocket and
HTTP URLs the Deepgram SDK requires.
Closes#4019
Now that the base TTSService and STTService handle Language enum
conversion at init time, subclasses no longer need to convert in their
own __init__ methods. Remove conversion calls from hardcoded defaults,
params paths, and deprecated direct arg paths across 22 service files.
Services just pass raw Language enums and let the base class convert
via language_to_service_language() polymorphic dispatch.
When a Language enum (e.g. Language.ES) is passed via
settings=Service.Settings(language=Language.ES), it gets stored as-is
without conversion to the service-specific code. The base
_update_settings() handles this for runtime updates, but at init time
apply_update() copies the raw enum. This causes API errors because
services send the unconverted enum value.
Add language conversion in TTSService.__init__ and STTService.__init__
after super().__init__(), using the subclass language_to_service_language()
via normal method resolution.
