Version 3.4.1

Changes:

• BREAKING CHANGE: AT&T STT API IS BEING SHUT DOWN SOON. (source)
  • For now, the recognize_att function will keep working, until the API itself is shut down.
  • It is best to transition over to IBM, Wit.ai, Google, CMU Sphinx, Bing Voice, or api.ai as soon as possible.
  • In most cases, you can simply rename recognize_att to a different service like recognize_ibm, then generate new API keys/tokens for it.
• DEPRECATED CLASS: WavFile has been renamed to AudioFile.
  • WavFile will continue to work for the foreseeable future. New code should use AudioFile.
  • AudioFile is the same as WavFile, but in addition to WAV, it also supports AIFF and FLAC files!
• New api.ai support, courtesy of @sbraden! See recognize_api in the library reference.
• New Microsoft Bing Voice Recognition API support! See recognize_bing in the library reference.
• Support for 8-bit unsigned WAV audio (thanks to @zhaoqf123 for reporting!).
• Faster, upgraded FLAC binaries, with Linux binaries using Holy Build Box for maximum distro compatibility..
• Updated setup process for Wit.ai.
• Update phrase retrieval for recognize_ibm, courtesy of Bhavik Shah from IBM.
• Documentation improvements and code cleanup.
• Clearer licensing information - see the README.

As always, you can upgrade with pip install --upgrade speechrecognition.

Version 3.3.3

Changes:

• Tiny fix to some error checking.
• The version number is all 3's now. This is pretty OK.

Version 3.3.2

Bugfix release!

• Fix exception_on_overflow shenanigans. This version will eliminate those pesky ValueErrors.
• The overflow error should well and truly be gone now.

Special thanks to @michaelpri10 for reporting the exception_on_overflow bug.

Version 3.3.1

Fix for list_microphone_names, courtesy of @ibutra. Fully compatible with 3.3.0.

See #85 for more details!

Version 3.3.0

Major changes since 3.2.1:

• Possible backward incompatibility: if PyAudio is not installed, Microphone now throws an AttributeError when created rather than not being defined.
  • This only requires changes if you are explicitly testing for the existance of the class, using something like hasattr or getattr.
• More robust error handling - always clean up PyAudio resources, no matter what error conditions arise.
• Better error checking - always verify PyAudio version.

Version 3.2.1

Changes since 3.2.0:

• Significantly improved and reorganized documentation.
• Fix for overflow issue, courtesy of @jbwincek.

Version 3.2.0

Major changes since 3.1.3:

• Support for recognition using CMU Sphinx - do speech recognition while offline!
  • English supported out of the box; French and Mandarin available for download. See the README for details.
• Automatic sample rate/sample width conversions; users shouldn't have to worry about audio formats at all.
• Lots of documentation improvements.

Version 3.1.3

• Work around an obscure standard library issue.
  • Doesn't work on big endian systems - use Python 3.5 to get the proper bugfix for that.
• Handle stereo WAV files correctly.

Version 3.1.2

Changes since 3.1.0:

• Update documentation to account for new releases of Python, PyInstaller, and PyAudio.
  • The new PyAudio version fixes an obscure overflow issue and also makes installation much easier on all platforms.
  • New documentation for the updated PyAudio installation process.
• General documentation improvements.
• Handle errors better and add additional error checks.
