I get an error when trying to synthesize speech over ~1500 characters (4MiB) despite documentation stating the limit is 5000 characters. There is no problem synthesizing 5000 characters when using MP3 encoding (output file size: 1.2MB) on the same text, indicating that the problem is definitely just the larger file size when using LINEAR16 encoding (output file size: >13MB). This seems to be related to issues googleapis/google-cloud-python#5819, googleapis/google-cloud-python#5574
