Speech Server is an English (United States) product that includes Speech Server Developer Tools. Speech Server supports operation and application development with English (United States) operating systems using English (United States) locales only. Within that environment, it is possible to create applications for English (United States) and other languages. The Setup text, documentation, and Speech Server management modules and logs are all written in English (United States).
You must install at least one language pack to obtain support for user interaction. Speech Server does not support user interaction in any specific language by default. Support for user interaction in additional languages can be added by installing additional language packs.
User Language Support
The following table lists the user languages for which Speech Server provides language packs. For each language, the table shows the language???s name, country/region, culture name, and LCID decimal value. For each language, the table also shows whether the language pack???s resources support speech recognition, DTMF recognition, and text-to-speech synthesis for applications that you develop using Speech Server Developer Tools.

User Language Support Issues
Because certain features of Speech Server Developer Tools depend on the presence of a speech recognition engine, installing only language packs that do not support speech recognition on your development computer can cause a number of application development issues. If no language packs that support speech recognition are installed on your computer:
- Conversational Grammar Builder will fail to compile conversational grammars, including DTMF grammars that are built using Conversational Grammar Builder.
- Speech Grammar Editor will not validate DTMF grammars.
- The Custom Application Lexicon Editor will not display word pronunciations.
- Automatic prompt alignment for wav files imported into a prompts project will fail.
- Running speech applications that contain components which require the presence of a speech engine (for example, a QuestionAnswerActivity with an attached grammar) will throw an exception.
The first two issues might be unexpected when developing applications designed to use only DTMF and TTS. To avoid these issues during application development, you must install at least one language pack that contains a speech recognition engine, regardless of whether you develop an application using that language. For example, if you plan to use Conversational Grammar Builder to develop a DTMF grammar for a Portuguese (Brazil) application, in addition to installing the Portuguese (Brazil) language pack on your development computer, you must also install one of the following language packs: English (United Kingdom); English (United States); French (Canada); German (Germany); or Spanish (United States).
The last three issues are expected behavior when developing applications that do not require speech recognition.
All of these issues apply only to development environments. For example, a Portuguese (Brazil) application can successfully use a compiled Portuguese (Brazil) DTMF grammar on a production server on which only the Portuguese (Brazil) language pack is installed.
