How is the merkle root verified if the mempools may be different? Youll be able to perform cool things such as load(), pause(), play(), playbackRate+, etc. The call to synthesizer.close() is needed for synthesis to function correctly. * @param {string} fileMany web apps require file inputs to handle files within the front end or upload them to the back end. If the voice does not speak the language of the input text, the Speech service won't output synthesized audio. The decodeAudioData() method of the BaseAudioContext Interface is used to asynchronously decode audio file data contained in an ArrayBuffer.In this case the ArrayBuffer is loaded from XMLHttpRequest and FileReader.The decoded AudioBuffer is resampled to the AudioContext's sampling rate, then passed to a callback or promise. Run the program. OCS First, remove AudioConfig, because you'll manage the output behavior manually from this point onward for increased control.

Web Audio API has a significant advantage; it offers more flexibility and control over the sound. Passing None for AudioConfig, rather than omitting it as you did in the previous speaker output example, will not play the audio by default on the current active output device. The audio file has no text, so set the requests responseType to arraybuffer, which interprets that audio file as a binary file.
