def LexFormats():\r
  """Makes the phoneme conversion tables of each format.\r
     Each table has string to phoneme entries and phoneme\r
     to string entries.  The string to phoneme entries are\r
     used when converting OUT of that format, and the\r
     phoneme to string entries are used when converting IN\r
     (so you can recognise phonemes you don't support and\r
     convert them to something else).  By default, a tuple\r
     of the form (string,phoneme) will create entries in\r
     BOTH directions; one-directional entries are created\r
     via (string,phoneme,False) or (phoneme,string,False).\r
     The makeDic function checks the keys are unique.\r
     \r
     First parameter is always a description of the\r
     format, then come the phoneme entries as described\r
     above, then any additional settings:\r
\r
       stress_comes_before_vowel (default False means any\r
       stress mark goes AFTER the affected vowel; set to\r
       True if the format requires stress placed before)\r
\r
       word_separator (default same as phoneme_separator)\r
       phoneme_separator (default " ")\r
       clause_separator (default newline)\r
\r
       (For a special case, clause_separator can also be\r
        set to a function.  If that happens, the function\r
        will be called whenever lexconvert needs to output\r
        a list of (lists of words) in this format.  See\r
        bbcmicro for an example function clause_separator)\r
\r
       safe_to_drop_characters (default False, can be a\r
       string of safe characters or True = all; controls\r
       warnings when unrecognised characters are found)\r
\r
       approximate_missing (default False) - if True,\r
       makeDic will attempt to compensate for missing\r
       phonemes by approximating them to others, instead of\r
       warning about them.  This is useful for American codes\r
       that can't cope with all the British English phonemes.\r
       (Approximation is done automatically anyway in the\r
       case of variant phonemes; approximate_missing adds in\r
       some additional approximations - see comments in code)\r
\r
       cleanup_regexps (default none) - optional list of\r
       (search,replace) regular expressions to "clean up"\r
       after converting each word INTO this format\r
       cleanup_func (default none) - optional special-case\r
       function to pass result through after cleanup_regexps\r
\r
       cvtOut_regexps (default none) - optional list of\r
       (search,replace) regular expressions to "clean up"\r
       before starting to convert OUT of this format\r
       cvtOut_func (default none) - optional special-case\r
       function to pass through before any cvtOut_regexps\r
  \r
       inline_format (default "%s") the format string for\r
       printing a word with --phones or --phones2phones\r
       (can be used to put markup around each word)\r
       (can also be a function taking the phonetic word\r
        and returning the resulting string, e.g. bbcmicro)\r
\r
       output_is_binary (default False) - True if the output\r
       is almost certainly unsuitable for a terminal; will\r
       cause lexconvert to refuse to print phonemes unless\r
       its standard output is redirected to a file or pipe\r
       (affects the --phones and --phones2phones options)\r
\r
       inline_header (default none) text to print first\r
         when outputting from --phones or --phones2phones\r
       inline_footer (default none) text to print last\r
       inline_oneoff_header (default none) text to print\r
         before inline_header on the first time only\r
\r
       lex_filename - filename of a lexicon file.  If this\r
       is not specified, there is no support for writing a\r
       lexicon in this format: there can still be READ\r
       support if you define lex_read_function to open the\r
       lexicon by itself, but otherwise the format can be\r
       used only with --phones and --phones2phones.\r
\r
       lex_entry_format - format string for writing each\r
       (word, pronunciation) entry to the lexicon file.\r
       This is also needed for lexicon-write support.\r
\r
       lex_header, lex_footer - optional strings to write\r
       at the beginning and at the end of the lexicon file\r
       (can also be functions that take the open file as a\r
        parameter, e.g. for bbcmicro; lex_footer is\r
        allowed to close the file if it needs to do\r
        something with it afterwards)\r
\r
       lex_word_case - optional "upper" or "lower" to\r
       force a particular case for lexicon words (not\r
       pronunciations - they're determined by the table).\r
       The default is to allow words to be in either case.\r
\r
       lex_type (default "") - used by the --formats\r
       option when summarising the support for each format\r
\r
       lex_read_function - Python function to READ the\r
       lexicon file and return a (word,phonemes) list.\r
       If this is not specified, there's no read support\r
       for lexicons in this format (but there can still be\r
       write support - see above - and you can still use\r
       --phones and --phones2phones).  If lex_filename is\r
       specified then this function will be given the open\r
       file as a parameter. """\r

    # Speech was written by David J. Hoskins and published by Superior Software.  It took 7.5k of RAM including 3.1k of samples (49 phonemes + 1 for fricatives at 64 bytes each, 4-bit ~5.5kHz), 2.2k of lexicon, and 2.2k of machine code; sounds "retro" by modern standards but quite impressive for the BBC Micro in 1985.  Samples are played by amplitude-modulating the BBC's tone generator.\r
    # If you use an emulator like BeebEm, you'll need diskimg/Speech.ssd.  This can be made from your original Speech disc, or you might be able to find one but beware of copyright!  Same goes with the ROM images included in BeebEm (you might want to delete ones you didn't have).  There has been considerable discussion over whether UK copyright law does or should allow "format-shifting" your own legally-purchased media, and I don't fully understand all the discussion so I don't want to give advice on it here.  The issue is "format-shifting" your legally-purchased BBC Micro ROM code and Speech disc to emulator images; IF this is all right then I suspect downloading someone else's copy is arguably allowed as long as you bought it legally "back in the day", but I'm not a solicitor so I don't know.\r
    # (Incidentally, yes I was the Silas Brown referred to in Beebug 11.1 p.59, 11.9 p.50/11.10 p.47 and 12.10 p.24, and, no, the question in the final issue wasn't quite how I put it, but all taken in good humour.)\r
    # lexconvert's --phones bbcmicro option creates *SPEAK commands which you can type into the BBC Micro or paste into an emulator, either at the BASIC prompt, or in a listing with line numbers provided by AUTO.  You have to load the Speech program first of course.\r
    # To script this on BeebEm, first turn off the Speech disc's boot option (by turning off File / Disc options / Write protect and entering "*OPT 4,0"; use "*OPT 4,3" if you want it back later; if you prefer to edit the disk image outside of the emulator then change byte 0x106 from 0x33 to 0x03), and then you can do (e.g. on a Mac) open /usr/local/BeebEm3/diskimg/Speech.ssd && sleep 1 && (echo '*SPEECH';python lexconvert.py --phones bbcmicro "Greetings from 19 85") | pbcopy && osascript -e 'tell application "System Events" to keystroke "v" using command down'\r

This option is made more complicated by the fact that different versions of eSpeak may space the phoneme output differently, for example when handling numbers; if your eSpeak version is not recognised then all numbers are unannotated. Anyway you are advised not to rely on this option working with the new development NG versions of eSpeak. If the version you have behaves unexpectedly, words and phonemes output might lose synchronisation. However this option is believed to be stable when used with simple text and the original eSpeak.\r
