Frequently Asked Questions about TOEFL® Practice Online
Automated Scoring for Speaking
How were my responses scored? Your responses were scored by a computer using a program specifically designed as an automated scoring system for the TOEFL Practice Online Speaking test. The SpeechRater™ computer program uses speech recognition and analysis technology to analyze your responses. The important features of your spoken responses that are analyzed to produce your scores are Pronunciation, Fluency, Vocabulary, and Grammar.
Why are responses to the TOEFL Practice Online Speaking test rated by a computer? Using a computer instead of a human rater allows ETS to report your score on the Practice test within minutes.
How is my TOEFL Practice Online Speaking test score different from a TOEFL iBT Speaking score? Both the TOEFL Practice Online Speaking test and TOEFL iBT Speaking report your score on a scale of 0 to 30. However, the scores differ in two distinct ways: (1) the Practice test was scored by a computer rather than by a human rater and (2) the Practice test was scored by evaluating some, but not all, of the features evaluated by human raters for the TOEFL iBT Speaking test.
How is SpeechRater automated scoring different from human rater scoring? SpeechRater scoring is an automated prediction of a score a human rater would assign for the same response. The score is produced by combining the evaluation of several important features of each response (pronunciation, fluency, vocabulary, and grammar.) Together these features cover part of the scoring criteria used by human raters to score TOEFL iBT Speaking test. Human raters scoring TOEFL iBT evaluate each response in the areas of Delivery (pronunciation, rhythm, intonation, rate of speech, pause structure, fluidity), Language Use (vocabulary and grammar), and Topic Development (content and coherence.)* While SpeechRater analyzes features of Delivery and Language Use, it is currently limited in its evaluation of Topic Development features. In general, SpeechRater scoring is based on a subset of the criteria currently evaluated by human raters for TOEFL iBT Speaking test.
How do I get the most benefit from my TOEFL Practice Online Speaking score? A number of circumstances could cause this score to be a poor predictor of the scores human raters would have assigned your responses. Speakers who respond casually or carelessly to the speaking tasks, such as by responding with rehearsed speech that is not based on the speaking task, by responding in your native language, by reading from texts or notes, or by providing partial or incomplete responses are more likely to receive inaccurate scores. On the other hand, speakers who respond to the tasks seriously, as they would during a TOEFL iBT testing situation, are more likely to obtain a score reflecting their performance on practice speaking tasks that are similar to TOEFL iBT tasks.
How does computer scoring work? Your responses to each of the six speaking questions are recorded and sent to ETS where they are analyzed by SpeechRater, the automated speech recognition and analysis software system designed especially for TOEFL Speaking Practice test scoring. In developing the system, numerous responses to TOEFL Speaking Practice test questions were processed to establish a scoring model that defined the relationship between scores by human raters and the features of your responses (Pronunciation, Fluency, Vocabulary and Grammar) that are analyzed by SpeechRater. This scoring model was then slightly modified to reflect language experts judgments about how the score and important features of a response should be related. This modified scoring model is used to determine your score on each of the six tasks, which are then added together. The final score is converted to a 0-30 scale.
Has the computer scoring been reviewed by experts? Language learning specialists and testing experts, both internal and external to ETS, were invited to advise and participate in selecting the speech features used to compute automated scores. The features currently used in the computer scoring were determined by these experts to represent important aspects of the scoring rubrics used by the TOEFL iBT Speaking test. The resulting combination of features was determined to provide an acceptable overall evaluation of spoken responses for use in the TOEFL Practice test.
Is my TOEFL Speaking Practice test score a prediction of my score on TOEFL iBT Speaking? While these practice materials are designed to help you better prepare for the TOEFL iBT Speaking, the score you receive on the practice materials may not be the same as what you would receive on the TOEFL iBT Speaking. Studies have not yet been completed to compare performance on the TOEFL Practice test and the TOEFL iBT Speaking test. Until such studies are completed it will not be known how closely TOEFL Speaking Practice scores predict TOEFL iBT Speaking scores.
