<div>Dear Alex,</div>
<div> As far as I can see, MLT is doing what you want. Running on your six line sample, I get three turns for the child. It is true that it is not necessary to include the [+ trn] postcode. I’ll fix that part of the manual.</div>

<div>
<div dir="ltr">Dear Chibolters,<br>
<br>
We would like to have separate counts for both utterances and turns, taking into account linguistic, verbal, and non-verbal contributions. For example:<br>
<br>
<div>*CHI: 0. <br>
</div>
<span>
<div>%act: points to a cookie<br>
</div>
</span>*MOT: okay .
<div>*CHI: &baba .</div>
<div>*MOT: go for it .</div>
<div>*CHI: baby .</div>
<span></span><br>
We see in this example:<br>
- 3 turns by the child: 1 non-verbal (pointing), 1 verbal non-linguistic (&baba), and 1 linguistic (baby);
<br>
- 2 utterances by the child (because utterances cannot be non-verbal): 1 verbal non-linguistic (&baba), and 1 linguistic (baby)<br>
<div><br>
</div>
MLT on the sample above yields 3 utterances and 3 turns. If we MOR it and MLU the output, then we find 1 utterance. Is there a simple way to extract the other subtypes? Or should we add by hand codes such as:<br>
<br>
<div>*CHI: 0. [- verbal]<br>
</div>
<span>
<div>%act: points to a cookie<br>
<span>
<div>%<span>trn</span>: $TUR</div>
</span></div>
</span>*MOT: okay .
<div>*CHI: &baba .</div>
<div>*MOT: go for it .</div>
<div>*CHI: baby . <br>
<br>
</div>
<div>To exclude non-verbal turns from MLT:<br>
</div>
<div>
<div>> MLT -s"[- verbal]" @ </div>
<span>

Incidentally, the CLAN manual does refer to non-verbal turns twice; on p. 34:<br>
<br>

<div style="margin-left: 40px;"><i></i></div>
<p style="margin-left: 40px;"><i><span style="font-size:12pt;font-family:"Times"">The third analysis we will perform is to compute MLT (Mean Length of Turn) for both child and mother. Note that, unlike the MLU program, the CLAN program MLT includes the symbols
xxx and yyy in all counts. Thus, utterances that consist of only unintelligible vocal material still constitute turns, as do nonverbal turns indicated by the postcode [+
<span>trn</span>] as illustrated in the following example: </span></i></p>
<div style="margin-left: 40px;"><i></i></div>
<p style="margin-left: 40px;"><i><span style="font-size:10pt;font-family:"Courier";font-weight:700">*CHI: 0.[+

<p style="margin-left: 40px;"><i><span style="font-size:12pt;font-family:"Times"">We can use a single command to run our complete analysis and put all the results into a single file.

<p><br>
</p>
<p>However, as far as we can see, with or without [+ trn] one gets the same results using the example provided in the manual (<i><span style="font-size:10pt;font-family:"Courier";font-weight:700">*CHI: 0.[+
