The resume() method of the AudioContext Interface resumes the progression of time in an audio context that has previously been suspended.
The MediaRecorder.resume() method (part of the MediaRecorder API) is used to resume media recording when it has been previously paused.
The resume() method of the OfflineAudioContext interface resumes the progression of time in an audio context that has been suspended. The promise resolves immediately because the OfflineAudioContext does not require the audio hardware. If the context is not currently suspended or the rendering has not started, the promise is rejected with InvalidStateError.
The resume() method of the SpeechSynthesis interface puts the SpeechSynthesis object into a non-paused state: resumes it if it was already paused.
