Multilingual Speech Recognition Database for Motor Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicles lack a convenient and efficient speech interface that can handle commands in multiple languages, making operation cumbersome for users who may not speak the dominant language of the vehicle's system.
Innovation Solution
A motor vehicle equipped with a speech interface that includes a speech recognition database and engine capable of comparing acoustic commands in multiple languages, along with a multilingual grammar module, grapheme-to-phoneme modules, and a language selection module to automatically determine and switch between languages based on user input, enabling seamless operation regardless of language proficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a speech interface is implemented in a motor vehicle, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The speech interface is designed to handle commands in multiple languages (first language and at least second language) within a single system. The speech recognition database stores commands in multiple language versions, and the speech recognition engine automatically compares acoustic inputs against all stored versions, enabling the system to serve users speaking different languages without requiring separate systems for each language.
2Adaptability or versatility
If a multilingual speech recognition database is implemented, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The speech recognition database is organized by separating commands and command components into different versions according to pronunciation in different languages. The database structure allows storage of substantial portions of commands in multiple language versions while maintaining an organized, accessible format that enables the speech recognition engine to efficiently compare acoustic inputs against the appropriate language versions.
3Ease of operation
If automatic language detection is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The speech recognition engine automatically detects which language version(s) to compare against by analyzing the acoustic input and comparing it against the stored commands in the speech recognition database. The system self-determines the appropriate language matching without requiring user intervention or manual language selection, thereby improving ease of operation while the automation itself adds to device complexity.

AI summary
A motor vehicle has a speech interface for an acoustic input of commands for operating the motor vehicle or a module of the motor vehicle. The speech interface includes a speech recognition database in which a substantial portion of commands or command components, which can be input, are stored in a version according to a pronunciation in a first language and in a version according to a pronunciation in at least a second language, and a speech recognition engine for automatically comparing an acoustic command to commands and/or command components, which are stored in the speech recognition database, in a version according to the pronunciation in the first language and to commands and/or command components, which are stored in the speech recognition database, in a version according to the pronunciation in the second language.
