The most worthwhile segments are chosen automatically, by using word confidences and a cost model, and depending on the time budget. In budgeted transcription mode, the transcriber only corrects a subset of all segments, in order to save time.

A detailed explanation for how to use these features will be given in Section 3. This section shows a few examples of Sesla Transcriber’s features. 2 Illustration of Transcription Approaches
It allows either transcribing each segment from scratch or post-editing, and has logging features that allow detailed user studies. The user interface was designed to be easy to learn and efficient to use. Upon updating the cost model, the choice of segments is also updated in order to benefit from the improved cost estimates. The cost model is trained on-the-fly while the transcriber is working, starting from a transcriber-independent cost model for a new transcriber and over time predicting the particular transcriber more and more accurately. Errors are predicted using confidence scores from the automatic speech recognizer. To choose segments for correction, we employ predictive models that estimate the necessary correction time and the number of errors in every potential segment. , compared to the traditional, cost-insensitive approach of choosing low-confident segments from a fixed segmentation. Savings in human effort of 25% are reported in The locations and sizes of these segments are chosen such that the expected reduction of errors is maximized given the time budget, according to the Sesla method (Segmentation for Efficient Supervised Language Annotation) as described in The tool asks the user to specify a time-budget (for example, 30 minutes of annotation), and automatically chooses an appropriate number of segments for correction such that the time-budget is kept.

The general strategy is to focus only on those erroneous parts, and trust the speech recognizer for other parts, in order to reduce the amount of manual effort. The main innovation is a feature for budget-friendly transcription, that uses an automatically created transcript as a starting point, and guides the transcriber through the correction of a selection of segments that are likely to contain errors. translation, sentiment annotation, etc.). Besides correction of an erroneous speech transcript, the tool supports transcription from scratch, and more general forms of labeling (e.g. Our goal is to make this manual work as time-efficient and budget-friendly as possible. Sesla Transcriber is a tool for efficient speech transcription / labeling.
