Abstract: Methods, apparatus, and systems are provided such that a Public Safety Answering Point (PSAP) may utilize a new model to handle Open Line emergency calls, including audio optimization, automation, analysis, and presentation. Embodiments of the present disclosure assist with the difficult task of identifying background noise while trying to listen and talk to a caller, and give the best possible audio from the caller to the emergency call-taker or dispatcher. More particularly, an audio stream is split into at least two instances, with a first instance being optimized for speech intelligibility and provided to a call-taker or dispatcher and a second instance being provided for background sound analysis. Accordingly, the new PSAP Open Line model may allow for significantly more efficient emergency assessment, location, and management of resources.
