Method and system for mitigating delay in receiving audio stream during production of sound from audio stream

A system comprising:

• a transmitting device for transmitting an audio stream including an audio waveform;
• a receiving device for receiving the audio stream including audio production circuitry configured to produce sound using the audio waveform of the audio stream;
• processing circuitry of the transmitting device configured to analyze the audio stream and identify a modification segment of the audio waveform, the modification segment being a segment of the audio waveform where production of the audio waveform may be modified to mitigate a delay when the receiving device receives the audio stream by temporally extending the modification segment without substantially affecting clarify of the produced sound;
• and
• processing circuitry of the receiving device configured for driving the production of sound using the audio waveform based at least in part on the modification segment that was identified;
• wherein the audio stream includes metadata associated with the audio waveform that indicates a position of a specific type of sound included in the audio waveform;
• wherein the processing circuitry of the transmitting device is configured to analyze the associated metadata and identify modification segment having the position within the specific type of sound;
• and
• wherein the specific type of sound is phonemes having natural pauses, phonemes having voiceless glottal plosives, phonemes related to vowels, phonemes related to fricatives, quasi-stationary audio waveform segments of phonemes, middle audio waveform segments of phonemes, lip positions having natural pauses, or lip positions having voiceless glottal plosives.
