On Jan 11, The Wall Street Journal published an interview with President Trump that contained the following phrase:

With that being said, President Xi has been extremely generous with what he’s said, I like him a lot. I have a great relationship with him, as you know I have a great relationship with Prime Minister Abe of Japan and I probably have a very good relationship with Kim Jong Un of North Korea.

I have relationships with people, I think you people are surprised.

The White House subsequently denied this statement, claiming that the President rather said (emphasis mine):

I​'d probably have a very good relationship with Kim Jong Un of North Korea

WSJ responded by publishing audio recording that, in their opinion, supports their original transcript. This has been considered adequate evidence by many commentators, for example Newsweek. I, however, beg to differ.

Having listened to the recording carefully, it seems to me that Trump's I was followed by a glottal stop. Why is this important? T-glottalization commonly occurs in American English and I thought Trump could show similar yet less exhibited D-glottalization, which would perfectly resolve the whole controversy.

However, my brief research shows that this sound change is rarely mentioned by phonologists, and attributed mostly to African American speakers, such as this study from Houston area.

Not having reached a conclusion myself, my questions are:

  1. Am I correct transcribing Trump's words as [ʌɪʔ ˈprɒbəbli]?
  2. Is D-glottalization a thing for a New York white speaker, i.e. would he pronounce I'd as [ʌɪʔ]?

I'm going to show the acoustic signals that are on the tape. It's hard to be certain on this one because the normal cues that you'd look for are just very faint or hard to distinguish. I'd be surprised if a linguist comments decisively for the media about what the tape shows going strictly by the physical audio (they might infer using other techniques).

tl;dr you can't tell unless you're able to squint better than me. I can't see glottalization, but it wouldn't be expected anyways (it's normally a cue for coda [t], not [d]).

Below you'll see a spectrogram. This is gotten with the software Praat. I extracted the left channel and had Praat display a spectrogram using a window length of 5 ms and a dynamic range of 35.0 dB.

First, what are you seeing? The spectrogram shows acoustic energy by frequency, with darker spots corresponding to more energy. Between 15.696s and 15.877s is the phrase "and I" or "and I'd". Before that you'll see high frequency noise (sounds like a click or sucking sound). After that you see about 90 ms of silence, followed by the release of the p (noise in the range of the first four vocal formants).

There are three types of cues you can look at (maybe more).

  1. Formant transitions
  2. Presence/absence of glotallisation
  3. Stop closure duration

First, formant transitions. Focus on the syllable between 15.794s and 15.877s. You'll see two regions of periodic sound (regular pulses of energy) between around 400--800 Hz and 1400--1800 Hz. These are the first two formants (F1 and F2), and they are determined by the the shape of the oral cavity (created by jaw position and tongue shape). Comparing [a] and [i], F1 should be higher for [a], and F2 should be higher for [i]. So in the diphthong [ai], you are going to see F1 and F2 start out close, then F1 drops while F2 rises. Consonants also affect the shapes of the formants. In the Trump "big league" affair, it was clear that he was saying "big league" because velar consonants like [k] and [g] cause F2 and F3 to "pinch" together. Anyways, a labial consonant like [p] should cause all formants to drop. An alveolar consonant like [d] should cause F1 to drop, and F2 to become more central (close to where it would be for [a] or schwa). Since right before the disputed consonant (is he saying [dp] or [p]?) is [i], which is front and has a high F2, you would expect to see a drop in both F1 and F2 regardless of whether it was [d] or [p]. So I can't draw anything from formant transitions.

As for glottalization. That comes before [t] specifically, not [d] (in fact it makes [t] and [d] easier to tell apart). So we shouldn't expect glottalization. The longer pulse periods starting at 15.696s might be glottalization (he had paused). You don't see the pulses getting irregular as the contested consonant closure is formed, but you wouldn't expect them.

As for closure duration, 90 ms seems a bit long for a stop closure for someone who's speaking fast, so that'd be an argument in favor of [dp], but then again he might have paused for an instant to think what to say next, since he was speaking extemporaneously.

    Holy ####, amazing work! It seeing this kind of expertise at play which sustain the dream of EL&U. This is what we’re all here for. Thank you. I’ll leave the data-answer up a few days more if anyone else wants to take a crack at it. But I don’t think anyone is going to be able to one-up you here.

    If it helps you at all, the related question on Linguistics.se points to this recent analysis by Mark Liberman on LanguageLog, who in turn quotes Susan Lin in the Friends of Berkeley Linguistics Facebook group. They both, like you, land on “inconclusive from the audio evidence” but “lean towards I’d on the whole body of evidence”, in particular that Trump’s next sentence starts out “I would”, before he changes direction.

  • No doubt this is an excellent analysis of the recording, but , for those of us who don't understand the details, I can't actually see a conclusion, nor even an opinion, in plain English on whether he actually said "I" or "I'd" - although I may be missing it.

I'm going to try a little experiment here. I ask for the forbearance of my colleagues on EL&U. I want to share some data, but I do not have the expertise to interpret the data. So I want to make the data available in a Community Wiki answer so experts can weigh in on the data and perhaps draw some meaningful conclusions. You can vote up or down, but please consider holding off on delete votes for a day or two.

If you have any expertise in audio analysis, phonetics, phonology, or reading spectrograms, please feel free to edit this answer to include your interpretation. To avoid the risk of speculation or bald opining, please support your analysis with as much empirical evidence and authoritative references as you are able.


The audio the WSJ have made available of their interview with President Trump can be downloaded and analyzed in audio analysis tools.

The downloaded video can be accessed here, as well as just the audio track in either .m4a format or converted to .wav format.

Waveforms and Spectrograms

These are screenshots of waveforms (above) and spectrograms (below) of the four times Donald Trump said "I have ... relationship" with various people in his interview with the WSJ. The screenshots were taken in a software application called Sonic Visualizer.

The start and end times are approximate for each utterance of "I have", and the scaling/zooming is likely inconsistent, as it was done manually with no real experience in the software. But they'll give you a broad idea of where to start for your own analysis.

The bolded parts of the text indicate approximately what words are represented in the corresponding screenshot. The sections were calibrated manually.

1. President Xi

Around 6 seconds in, President Trump says:

... President Xi ... I have a great relationship with him ...

    EL&U regulars: I'm trying an experiment here in collaborative answering. Please bear with this for a while. This answer can always be deleted later, but for now I ask as a favor that you hold off for a day or two. Meanwhile, anyone with any expertise in spectrogram reading, waveform analysis, or phonology, please feel free to edit your [justified! corroborated!] interpretations directly into this CW answer.

  • Nice to have actual data. But it's too difficult to extraplote from without any cues from the perceived sound. (In other words we'd need the words matched up somehow with the waveforms/spectrograms). Surprisingly, nobody can read spectrograms and waveforms and say what was said yet, Jan 16, 2018 at 21:39
  • @Araucaria I attempted that in this answer. The waveforms correspond to the 4 distinct instances of I have ... relationship[s] . Hence the invitation is to compare these 4 graphs of "similar words".

    Jan 16, 2018 at 21:41
  • @DanBron Yes, I did notice and appreciate that. But we'd need to know the point that the "I" began at, and the point that the [v] occured at etc, etc. Jan 16, 2018 at 21:43

To my ears, 45 says "I'd probably..." with an unaspirated d, hardly surprising before another stop in casual, hurried speech that elides most everything. The word would that hangs in the air following this sentence reinforces the conclusion that he said I'd rather than I.

    I'd go along with that, if only because I doubt very much that the POTUS is saying that he already has some kind of working relationship with Chairman Kim. The rising intonation and the use of the word probably supports it.

    Whatever he said, there ain't no glottalization at all involved here.

Am I correct transcribing Trump's words as [ʌɪʔ ˈprɒbəbli]?

More like [aɪd̚ prɑbəbli] , with an /aɪ/ diphthong, an /ɑ/ sound, and an unreleased d (see below)

Is D-glottalization a thing for a New York white speaker, i.e. would he pronounce I'd as [ʌɪʔ]?

My personal opinion is that linguists are wrong calling this sound a "glottal stop". it's an unreleased D, or simply "an unreleased X".

what can I do? -> [wət̚ kn ai du]
I had this -> [ai həd̚ ðɪs]
shop -> [ʃɑp̚]

Basically, one starts pronouncing the consonant, but stops in the stage when the air is shot from one's mouth. in the T or D case, one puts his tongue where the T/D are made (the alveolar ridge), then continues saying the next consonant, or simply stops there.

It happens in most, if not all, the North American accents, for all the stop consonants (/t/, /d/, /k/, /g/, /p/, /b/) before another consonant or at the end of the sentence.

  • I don't think you quite understand what a linguist would say about those sounds. You've got their putative analysis completely wrong. Any phoneticain would say that an unreleased plosive/plosive with a masked release is still that plosive regardless of what happens after the hold phase. As far as I know, no linguists have posited (or ever would posit) that this /d/ might be represented by a glottal stop. [There's no reason to suspect there's a [d] there anyhow]. See jlovgen's answer. Jan 16, 2018 at 21:28
  • You can’t really say that an /aɪ/ diphthong has an /ɑ/ sound for several reasons, one of which is that slashes are for phonemes (what one perceives in one's mind, mentally) not for phones (what was actually said, physically). Perhaps you meant to say that his /aɪ/ diphthong has an [ɑ] sound. Like all phonemes in any language, the actual pronunciation of the abstract /aɪ/ phonemic diphthong in English varies a great deal. It is quite possible that he is saying [ʌɪ] as was proposed; most North American speakers have Canadian Raising.

  • "You can’t really say that an /aɪ/ diphthong has an /ɑ/ sound for several reasons" - I never said it. the /ɑ/ refers to his transcription if the word "probably", which he used the British vowel, look closely. I corrected it to the American one.

  • @Araucaria for the/d/ sound, maybe. for the /t/ sound - definitely. I argue that the /t/-s in "white hat" (in any American Accent) are not "glottal stops" but they're just "unreleased T-s"
