TOBI, so far• English has pitch accents, which align with stressed

syllables in an utterance.

• We’ve seen two pitch accents:

1. H* : peak in F0

2. L* : trough in F0

• English also has boundary tones, which align with the ends of intonational phrases.

• There are also two of these:

1. H%

2. L%

• Boundary tones are not associated with a particular syllable.

For Example

L* H%

For Example #2

H* L%

Information• Note that there’s a tendency to accent new information in the discourse.

• 4 different patterns for 4 different contexts:

H*

H*: Manny came with Anna.

H*

H*: Manny came with Anna.

L*

L*: Manny came with Anna?

L*

L*: Manny came with Anna?

Question Formation• Note that not all questions end in L* H%.

• What’s the intonational difference between these two?

Did you see Bob?

L*H%

Where did you go?

H* L%

• The upsloping intonation only applies to yes/no questions.

• Also note: “Uptalk”

• = application of L* H% pattern to declarative sentences.

Break Indices• Intonation organizes utterances into phrases

• “chunks”

• Boundary tones mark the end of intonational phrases

• Intonational phrases are the largest phrases

• In the transcription of intonation, phrase boundaries are marked with Break Indices

• Hence, TOBI = Tones and Break Indices

• Break Indices are denoted by numbers

• 1 = break between words

• 4 = break between intonational phrases

Break Index Transcription

Tones: L* H%

Breaks: 1 1 1 4

0 Level Boundaries• 0 level boundaries are marked wherever there is clear coarticulation across a word boundary

• Also for flaps across word boundaries, as in “got it”

0 1 1 4

Downstepping• There can be more than one pitch accent within an intonational phrase.

• Successive H* accents tend to drift downward in F0 within an intonational phrase.

• = downdrift, or downstepping

• This provides further evidence for phrasal organization.

• Downstepped H* accents are denoted with a !H*

• Anna gave Manny a mango.

H* !H* !H* L%

• There’s a lovely, yellowish, old one.

H* !H* !H* L%

Downstepping Pitch Track

H* !H* !H* L%

=271 Hz =238 Hz =200 Hz

Intermediate Phrases• A downstepping pattern can be reset by the presence of an intermediate phrase boundary.

• Example:

It’s lovely, and yellowish, and it’s an old one.

H* !H* L- H* L-L%

• Intermediate phrase boundaries are marked with a break index of 3.

• At the end of each intermediate phrase is an phrase accent

• Either Low (L-) or High (H-)

Intermediate Phrase Transcription

H* !H* L- H* L-L%

1 1 1 3 1 1 0 1 4

One Phrase vs. Two Phrases• No intermediate phrase boundary:

“I” means insert.

H* H*L-L%

1 1 4

• An intermediate phrase boundary, with a L- phrase accent:

“I” means insert.

H* L- H*L-L%

3 1 4

• Note: intermediate sense of disjuncture, between word and intonational phrase.

One Phrase vs. Two Phrases• No intermediate phrase boundary:

Marianna made the marmalade.

L* L* H-H%

1 1 1 4

• An intermediate phrase boundary, with a H- phrase accent:

Marianna made the marmalade.

L* H- L* H-H%

3 1 1 4

Filling the Gap• Another feature of phrase accents is that they fill in the gap between the nuclear accent and the boundary of the intermediate phrase.

L* + H L- H%

1 0 1 1 4

Combinations• Different combinations of phrase accents and boundary

tones have different connotations.

1. L-L% Declarative sentences

2. H-H% Yes/No questions (usually)

3. L-H% Continuations

4. H-L% A “plateau” pattern

• Upstep: boundary tones after H- are higher than normal.

Upstepping

• H-H%

• H-L%

“My name is Marianna.”

A Chunking Reviewutterance

intonational phrase (intonational phrase) ...

intermediate phrase (intermediate phrase) ...

(pitch accent) nuclear accent

(stressed syllable) stressed syllable

Break Indices• 4 marks boundaries between intonational phrases

• associated with a boundary tone (H% or L%)

• sense of complete disjuncture

• 3 marks boundaries between intermediate phrases

• associated with a phrase accent (H- or L-)

• lesser sense of disjuncture

• 1 marks boundaries between words

• 0 marks non-boundaries between words

• (2 marks uncertainties or apparent mismatches)

• rarely used

Bitonal Pitch Accents• In addition to H* and L*, there are two bitonal pitch accents

• L + H*

• L* + H

• The starred element denotes the tone which is associated with the stressed syllable

• L + H* = high peak on stressed syllable, preceded by a sharp rise in pitch

• L* + H = low pitch target on stressed syllable, followed by a sharp rise in pitch

H* vs. L + H*• Marianna won it.

H*

L + H*

Note: informative vs. contrastive function

L* vs. L* + H• Only a millionaire.

• Marianna made the marmalade.

H* L* + H L- H%

L* L* H-H%

L + H* vs. L* + H• There’s a lovely one at Bloomingdale’s.

L* + H

L + H*

More Downstepping• Bitonal pitch accents can also undergo downstepping.

Pitch-Accents Round-up• There are four pitch accents:

• H*

• L*

• L + H*

• L* + H

• They attach to stressed syllables

• The final pitch accent in an intonational phrase is the nuclear accent.

• Generally perceived as more prominent.
