KTH Speech, Music and Hearing

Stockholm, Sweden

Prosodic measurements and question types in the Spontal corpus of Swedish dialogues


VariQ

Investigate and describe intonational variation in questions in spontaneousdialogue.

Is there a standard typeofquestion intonation?


Question intonation

  • Declarative => Interrogative

    ”You like apples.” vs. ”You like apples?”

  • Different questiontypes, different intonation

    Y/N questions: Wh-questions:

  • Where is the rise in conversationalspeech?


Spontal corpus

  • 60 hoursofdialogue / 120 half-hour sessions

  • Talk freelyaboutanything


Questionextraction

  • 24 dialoguesubset (= 12 hours)

  • Talkspurts based on voice-activity/silence

  • Orthographictranscriptions

  • Twoannotators tag ”questions”

    908 talkspurts withquestion tag

    600selected

    (Spontal balance, 2+ annotatorsagreeing)


Questionmarkup

  • Q1: [Y/N] [Wh] [Alt’s] [Other]

  • Q2: [Required] [Optional] [Prohibited]

  • Q3: [Forward] [Backward]

  • Q4: [Reported] [Direct]

Ser du attdetärhålibotten?

Do you see there’s a hole in the bottom?

Rising/Falling intonation

  • Y/Nfalling, Whrising (or flat)

  • Forwardfalling, Backwardrising (or flat) – butlarge variation


Rising/Falling intonation (cont.)

Jaha?

Oh yeah?

Tycker du inte?

Don’t you think?

Ärdetsant?

Is that true?

Vadsa du?

What’d you say?

Rising intonation signalling

non-understanding/non-acceptance?


Conclusions

  • Strengthsofcodingscheme:

    • General

    • Quick-and-easy

    • Orthogonal, allowsclusteringacross different dimensions

  • Interplayacross different dimensions

Optional + Backward

Other + Optional + Backward

More pitch variation

Slower

Attitude?

Uncertainty?

Non-agreement?


Thankyou for your attention!

What does that mean?


Rising/Falling intonation (cont.)

  • DIFF: Y/N falling, Wh rising; Backwardrising

    But… confusionwithsentence focus?

  • PROS: No significantdependencies…


Summary: Prosodicmeasures

  • Duration: Dependent on numberofalt’s

  • Speech rate: Slowreflectinguncertainty?

  • Pitch variation: Reflectingattitude?

  • Rising/Falling intonation:

    • DIFF: Dependent on sentence focus?

    • PROS: Not dependent on questiontype
