This blog post guides users in processing multi-channel audio recordings using the Symbl Async Audio URL API. To improve transcript accuracy, parameters such as speaker-separated channel audio processing, custom vocabulary, and phone mode can be added to the request body. The Conversation APIs provide insights on topics, follow-ups, questions, action-items, and trackers, which can be accessed after completing an asynchronous job. The APIs also offer additional features like summarization, entities detection, and sentiment analysis. Users can customize their experience by enabling or disabling various options such as speaker ratio, talk time, and silence analysis. The post concludes with the usage of Trackers for getting additional insights that cater to business needs.
