Make sure you have Internet connection and nothing is blocking Scratch domain - for example, proxy, firewall, antivirus or country-wide censorship.

For some reason body.buffer is undefined at scratch-vm/src/extensions/scratch3_text2speech/index.js speakAndWait.
なぜかしらcratch-vm/src/extensions/scratch3_text2speech/index.js speakAndWait内のbody.bufferがundefinedになってます。

@ericrosenbaum Where is body.buffer set? It seems like body is just a string with the data, not sure how it worked before. If requestType in the option is set as arraybuffer body should be ArrayBuffer.

@cwillisf Confirmed my theory was true:

• Add breakpoint at xhr/index.js L215 and scratch-vm/src/extensions/scratch3_text2speech/index.js L746
• On the first breakpoint, run xhr.responseType = "arraybuffer"; then resume
• On the second breakpoint, run sound.data.buffer = body; then resume
• Voice played

Looks like this will be fixed when scratchfoundation/scratch-vm#2891 goes in.
