a best effort version of the bot's output
- The `RTVIObserver` now emits `bot-output` messages based off
the new `AggregatedTextFrame`s (`bot-tts-text` and
`bot-llm-text` are still supported and generated, but
`bot-transcript` is now deprecated in lieu of this new, more
thorough, message).
- The new `RTVIBotOutputMessage` includes the fields:
- `spoken`: A boolean indicating whether the text was spoken by TTS
- `aggregated_by`: A string representing how the text was aggregated
("sentence", "word", "my custom aggregation")
- Introduced new fields to `RTVIObserver` to support the new
`bot-output` messaging:
- `bot_output_enabled`: Defaults to True. Set to false to disable
bot-output messages.
- `skip_aggregator_types`: Defaults to `None`. Set to a list of
strings that match aggregation types that should not be included
in bot-output messages. (Ex. `credit_card`)
`CartesiaTTSService`:
- Modified use of custom default text_aggregator to avoid deprecation warnings and push users
towards use of transformers or the `LLMTextProcessor`
- Added convenience methods for taking advantage of Cartesia's SSML tags: spell, emotion,
pauses, volume, and speed.
`RimeTTSService`:
- Modified use of custom default text_aggregator to avoid deprecation warnings and push users
towards use of transformers or the `LLMTextProcessor`
- Added convenience methods for taking advantage of Rime's customization options: spell,
pauses, pronunciations, and inline speed control.
Introduced `LLMTextProcessor`: A new processor meant to allow customization for how
LLMTextFrames should be aggregated and considered. It's purpose is to turn
`LLMTextFrame`s into `AggregatedTextFrame`s. By default, a TTSService will still
aggregate `LLMTextFrame`s by sentence for the service to consume. However, if you
wish to override how the llm text is aggregated, you should no longer override the
TTS's internal text_aggregator, but instead, insert this processor between your LLM
and TTS in the pipeline.
This frame introduces an `aggregated_by` field to describe the type of text included
in the frame and allows unspoken groupings of text to be pushed through the pipeline
and treated similar to TTSTextFrames.
