Bundling of Proofing Tools

It's very true that the costs of producing any of the language tools can vary enormously from one language to the next. In general, I expect that the smaller the language-base, the greater the cost. This is due to there being less choice resources available to choose from in terms of say lexical resources, voice or handwriting samples and computational linguists. Frankly, if you have a population under about 10 million, how many people do you really have devoted to collecting and analyzing the necessary data for creation of these tools?

In smaller or less-developed countries, the pattern is for interested parties: government, educational and media organizations to pool such resources to create a standard set of spell-checking, thesaurus or possibly voice-recognition tools. They can then tailor them to different APIs for Microsoft Office, OpenOffice or other platforms.
There are also some specialist companies who deal with the unique issues of low population language bases or even creole populations. I am sure that some of these are done as a labour of love by modern-day
Samuel Johnsons.
For the record, there is not just a single spell-checker for Office and multiple "dictionaries" for each language. Each language has a unique spell-checker (and grammar-checker and thesaurus and hyphenation and ...) DLL that comes paired with equally unique "LEX" files which store linguistic data. There is not even a single "LEX" format: it's really just a Microsoft convention for naming the resource files that accompany the checker-engine DLLs. And since Microsoft ships DLL/LEX sets produced by many other companies, the LEX format will vary according to the imagination and computational skills of each of these companies.

Nonetheless there are definitely issues with making even the Proofing Tool sets available to the market. Each version of Microsoft Office sees a new version of the PT CD released. The versions of Office and the PT CD must match
at installation time but you can subsequently upgrade Office and the older PT elements will still operate. Unfortunately, older versions of the PT CD generally disappear from warehouses long before their product lifetime has expired, and even the
Microsoft online store struggles to keep them in stock. For several years I had to send an email to a senior member of the Microsoft Word team to ask them to prompt distributors to keep these items in stock. I hope that Microsoft can figure a way to make these tools available over the web.
