The aerospace industry operates in a highly international and safety-critical environment. Precise and reliable communication is essential at all stages of system design, operation, and maintenance. Multinational teams, global supply chains, and international regulatory frameworks lead to the continuous creation and use of multilingual textual and spoken data, making language technologies an important component of modern aerospace infrastructure.
The relevance of language technologies in this domain is driven by three key factors: multilingualism, safety requirements, and technological complexity. Aerospace communication relies on highly specialized and standardized language, where ambiguity or inconsistency can have serious operational consequences. General-purpose language technologies are often insufficient in this context, as they are not designed to meet the strict accuracy, consistency, and controllability required in safety-critical applications.
The aim of this overview article is to examine language technologies applicable to the aerospace domain by outlining a set of solutions developed by Lingvanex.
Aerospace Domain as a Linguistic Environment
The aerospace domain is characterized by a highly specialized linguistic environment shaped by technical complexity, strict regulation, and safety-critical communication. Language used in aerospace contexts is predominantly formal, standardized, and tightly constrained, as it serves not only to convey information but also to minimize ambiguity and prevent misinterpretation.
Aerospace communication encompasses a wide range of text types, including technical documentation, engineering specifications, maintenance manuals, operational procedures, incident and safety reports, and regulatory standards. These texts are typically rich in domain-specific terminology, abbreviations, and formulaic expressions. In many cases, controlled language principles are applied to ensure consistency and clarity, particularly in documentation intended for international use.
Multilingualism further complicates this linguistic environment. Aerospace organizations routinely operate across linguistic and cultural boundaries, requiring accurate and consistent translation of critical information. Unlike general-purpose domains, aerospace language leaves little tolerance for variation in meaning, as even minor deviations can affect safety, compliance, or system performance. Consequently, any language technology applied in this domain must be capable of handling specialized terminology, standardized phrasing, and high demands for precision and reliability.
Overview of Lingvanex Language Technologies For Aerospace

On-Premise Speech Recognition
On-premise Speech Recognition provides automated conversion of spoken language into text within a secure, local infrastructure. In aerospace settings, this can be used to transcribe voice communications, technical briefings, training sessions, or recorded interactions. By processing audio data internally, organizations can analyze spoken content, extract insights, and integrate transcriptions with other language technologies while preserving data privacy. Key capabilities include:
- Support for 91 languages, covering major global and regional languages;
- Real-time speech recognition, suitable for live communications and time-critical scenarios;
- Speaker diarization, automatically distinguishing and labeling different speakers;

- Timestamps, enabling precise alignment of text with audio for analysis and review;
- Fully on-premise deployment, operating exclusively within the organization’s corporate infrastructure;
- High accuracy for technical and professional speech, including domain-specific terminology.
Data Anonymization Tool
Data Anonymization Tool automatically identifies and masks personal, sensitive, or confidential information within texts before they are processed by translation or analytics systems. This capability is critical in aerospace contexts where incident reports, maintenance logs, or human-generated documentation may contain personal data or proprietary details. Anonymization facilitates safe use of automated language processing while supporting compliance with data protection standards. Key features:
- Replaces original data with fictitious yet realistic-looking values that carry no real-world meaning. Commonly used to protect names, identifiers, contact details, and reference numbers while preserving document structure and readability.
- Substitutes identifiable information with pseudonyms or placeholders. The original data can be restored only using a secure, organization-controlled key, enabling controlled reversibility for audits or investigations.
- Reduces the level of detail in data to minimize identification risk. For example, exact values such as age, dates, or locations are converted into broader ranges or categories while preserving analytical usefulness.
- Introduces controlled “noise” into the data, slightly altering values to prevent accurate identification while maintaining overall statistical and linguistic patterns. Particularly useful for analytics and model training scenarios.
Named Entity Recognition
Named Entity Recognition (NER) identifies key entities in text, such as people, organizations, locations, equipment, components, dates, and reference numbers allowing organizations to extract critical information and streamline analysis for smarter, faster decision-making. Key features:
