Speech Collection of Styles (SPECS)

This is a dataset of keywords extracted from conversational-style speech and command-style speech and it is made up of 2 subsets: command keywords (ck) and conversational speech (cs). This dataset is intended solely for research on keyword recognition and speech style analysis. 

For each of the three datasets, we asked users to record themselves in a quiet environment, reciting given text excerpts with specific keywords inside them and saving the recordings as 16kHz 32-bit PCM WAVE files.

We added an additional folder of background noises, which is a copy from Google's Speech Commands set of background noises.

For command keywords (ck), the users were given 10 text examples, each containing 10 repetitions of the following keywords: on, no, up, off, down, stop, go, right, yes and left. They were asked to pronounce the examples as if answering a device, using an intonation similar to command-style speech; for instance, as if the device asked, "Lights up or lights down?" and they answered "Up!" ten times, with as much variation in intonation between the repetitions as they could produce.

ck sentences:

1) On! (10 times) 

2) No! (10 times) 

3) Up! (10 times) 

4) Off! (10 times) 

5) Down! (10 times) 

6) Stop! (10 times) 

7) Go! (10 times) 

8) Right! (10 times) 

9) Yes! (10 times) 

10) Left! (10 times)

For conversational speech (cs), users were given 20 more elaborate text examples such as this one: "She put the book on the table. No other books were there. She then looked up to her mum.". They were asked to recite the examples in their normal speaking tone as if they were telling a story to a friend. The recordings for CS contained a total of 10 instances of the same keywords mentioned for CM.
