Abstract: Provided are computer systems and methods for automatic generation of natural-sounding audio content from a variety of input data. The proposed systems and methods address several technical challenges observed in previous attempts to apply machine learning to this task. In particular, when applied to task of automatic audio content generation, traditional large models such as large language models (LLMs) or similar often produced audio content that sounded unnatural due to issues such as preachy tones, excessive flattery, awkward transitions, monotone delivery, and/or limited conversation length. These drawbacks made the generated dialogues feel less engaging and realistic.

Abstract: Disclosed is an amphiphilic graphene oxide (GO) temperature-resistant foam stabilizer for maintaining a wide pH range and a preparation method thereof. The amphiphilic GO is produced by dispersing GO in an ice-water bath, then sequentially adding a graphene oxide dispersion liquid, solid paraffin, emulsifier, and intercalation agent using a template method for emulsification and solidification. After washing and filtration, GO-coated paraffin microspheres are obtained. The microspheres are treated with hydrolyzed silane coupling agent, and further reacted with an amino modifier. GO-coated paraffin microspheres are dissolved completely in chloroform, followed by multiple centrifugation washes and freeze-drying to yield the foam stabilizer. The foam stabilizer has improved foam stability under high-temperature conditions across a wide pH range. It also possesses favorable interfacial activity and demonstrates a synergistic foaming effect with foaming agents.
