Use this interface to transcribe spoken Luxembourgish audio recordings into propperly written text adhering to the current spelling rules. Either upload an audio file (wav, mp3 or mp4) or use the microphone to record some audio. Hit Transcribe! After a certain time, the text will appear below. You can also try the examples.

Available options

Several audio input languages are available (default: Luxembourgish). If the recording contains more than one speaker, setting diarization to ‚On‘ will separate the text of every speaker in the recording along with time codes for their turns. Note that diarization adds some extra time to the recognition process. Three output formats are available: plain text (txt), SubRip Subtitles (srt), JSON (with or without time codes for words) and Praat TextGrid. These files can be downloaded through the link below the transcription. The recognition duration sums up to approximately 10 to 20% of the duration of the audio file. Once the recognition process has started, an estimated time and as well as a timer will be displayed to keep track of the progress. As an experimental feature translation to other languages has been added, which can output the recognized text in English, German, Portuguese or French. Note that these translations take more time to run and are only available for short audio files (up to few minutes).

The maximal size for upload is 500 MB (for audio in wav format and a sampling frequency of 16000 Hz).

Note that the actual speech recognition recognition is run on a GPU server outside Europe. At any time of the recognition, we do not have access to the uploaded audio files. After completion of the recognition, all files will be deleted immediately. Do not upload recordings with sensitive data.
