Dual Channel Support for Conversational Summarization / Improved Timestamps

We’ve made updates to our Conversational Summarization model to support dual-channel files. Effective immediately, dual_channel may be set to True when summary_model is set to conversational.

We've made significant improvements to timestamps for non-English audio. Timestamps are now typically accurate between 0 and 100 milliseconds. This improvement is effective immediately for all non-English audio files submitted to AssemblyAI for transcription.
