Extract text from Speech grammar files (GRXML)
To convert GRXML Grammar files to another format, you need Dragon NaturallySpeaking or other Developer software.
To convert other file formats to the "Speech Recognition Grammar XML" file type, you need software like Dragon NaturallySpeaking or a similar tool.
A .grxml file is an XML-based data file used to define speech recognition grammars. It follows the W3C Speech Recognition Grammar Specification (SRGS) standard. These files tell a speech engine, such as an Interactive Voice Response (IVR) telephone system, exactly what words or phrases to listen for and how to process them. They are heavily utilized in enterprise telephony systems and desktop voice-control software.
The primary software used to compile and process these files is Dragon NaturallySpeaking by Nuance Communications, alongside various enterprise IVR development environments. You can learn more about the underlying standard on Wikipedia's SRGS page.
The main disadvantage of the .grxml format is its rigid and highly verbose structure. Because it relies on strict XML namespaces and deeply nested logic trees, viewing these files often results in a massive, unreadable wall of code. Users typically need to convert these files to extract the raw vocabulary lists, audit the voice commands, or migrate speech rules to a more modern, lightweight data structure.
The best target formats for conversion are standard XML, plain TXT, or JSON. Converting to JSON or TXT makes the vocabulary readable and easier for developers to parse, though the specific voice engine compilation logic and phonetic weightings may be lost during the extraction.
This file format is difficult to accurately convert because the grammar logic is deeply tied to the specific speech recognition engine it was written for. Standard online converters fail to process the proprietary namespaces and syntax rules often injected by specific telephony vendors. Often, only the original IVR software can properly read or export the compiled data. However, just drag and drop your file to identify the format, view it, and convert it when possible. convert.guru can still inspect the file, bypass the compilation requirements, and show the raw text or internal content so you can recover your data.
Convert.Guru analyzes your GRXML file, detects the exact format, and lets you read the text inside.
Users also converted NWV, MTI and WML files.
If you want to convert GRXML file to , you can use Dragon NaturallySpeaking or similar software from the "Speech Recognition Grammar Rules" category. In the File menu, look for Save As… or Export….
To convert files to GRXML, try Dragon NaturallySpeaking or another comparable tool in the "Speech Recognition Grammar Rules" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our GRXML converter.
