Phone Number Entity Dataset

Dataset Release for Phone Number Entity capture task

About

There are two tracks here, and together they explore the task of capturing phone numbers from human speech. As per our knowledge this is the first public dataset for capturing numeric-sequence entities from speech. Each track consists of 2 (Indian English) speakers speaking out 75 phone numbers each:

1. one track has phone numbers spoken in a single utterance, and
2. the other track has phone numbers split across two utterances with a (4,6) split of digits

The audios were recorded over a telephony line.

Download and Usage

The tracks can be downloaded by clicking on these links:

• single-turn.zip
• two-turns.zip

Uses

A phone-number sequence is what we call a complex entity, and human speech tends to express such entities in different ways. These range from small pauses within the utterance, to breaking the entity into smaller, simpler pieces. If such patterns are a naturalistic way of speaking, then shouldn't Spoken Dialog Systems model this into their workings ? This dataset is a step towards exploring what such systems look like, and evaluating how they would do in the real-world.

A simple experiment with existing ASR systems would be to evaluate them on each track. The emphasis here is not on competitive performance between systems, but on each system across the tracks - how much better is the entity-capture task, when we model patterns in human speech ?
