Overview
Use the Speech framework to recognize spoken words in recorded or live audio. The keyboard’s dictation support uses speech recognition to translate audio content into text.

Oct 07, 2019 macOS Catalina introduces Voice Control, a new way to fully control your Mac entirely with your voice. Voice Control uses the Siri speech-recognition engine to improve on the Enhanced Dictation feature available in earlier versions of macOS. Speech recognition is just one of the macOS speech technologies. The speech synthesis technology allows applications to “pronounce” written text in U.S. English and over 25 other languages, with a number of different voices and dialects for each language (NSSpeech Synthesizer is the Cocoa interface to this technology).
You can perform speech recognition in many languages, but each SFSpeechRecognizer
object operates on a single language. On-device speech recognition is available for some languages, but the framework also relies on Apple’s servers for speech recognition. Always assume that performing speech recognition requires a network connection.

Mac os x link dynamic library ldd file. The versionless symlinks are generally so that the linker selects the most-current version, at which time new binaries should be linked to the soname of the library pointed to by that link.Kevin BarryPS Generally the soname won't change unless the API changes; this dynamic loading problem is intentional in that sense. That means a symlink probably won't fool ld.so. If the api hasn't change from libcrypto.so.6/libssl.so.6 to the one you have you can just symlink the name to yours and it should workAs far as I know binaries are linked to the soname, which is hard-coded into the library.
