A new report about Apple Inc.’s voice-recognition software Siri concludes what many users have been saying for a while: It doesn’t work all that well.

Of 1,600 common searches, the speech technology accurately resolved the request 62 percent of the time on a loud street and 68 percent in a quieter setting, according to a report released today by Piper Jaffray Cos., the Minneapolis-based investment bank. The report graded the technology “D” for accuracy, while predicting it will improve as more features are added.
