Your trick is similar to a strategy used in the valsalva hypothesis book: http://www.amazon.com/Understanding-Controlling-Stuttering-Comprehensive-Hypothesis/dp/1929773242/ref=sr_1_8?ie=UTF8&qid=1448938820&sr=8-8&keywords=stuttering The author likens speaking to a proper golf swing in that you have to 'swing through' to reach your target (usually the vowel sound in a word) instead of using effort to try to push through the block.
