Real-time tone feedback in video conferencing

One or more non-transitory computer-readable media storing one or more sequences of instructions which, when executed, cause a computer system to execute:

• using a computer system and under stored program control, receiving electronic digital data representing input time-correlated speech data and video data;
• by the computer system, determining a first text sequence corresponding to the input time-correlated speech data, the first text sequence comprising unstructured natural language text;
• by the computer system, determining a syntactic structure data associated with the first text sequence;
• by the computer system, inputting the time-correlated video data and the syntactic structure data associated with the first text sequence into one or more machine-learning models, the machine-learning models having been trained to produce, and producing, an output of one or more scores for at least a portion of the time-correlated video data and first text sequence;
• by the computer system, transforming the output of the one or more scores to yield an output set of summary points and suggestions;
• by the computer system, transmitting a graphical element of the output set of summary points and suggestions to a computing device, wherein rendering the graphical element using presentation functions of the computing device causes displaying the graphical element at the computing device.
