ConversationAlign Introduction.RmdA good conversation is a cooperative endeavor where both parties
modify the form and content of their own production to align with each
other. This is a phenomenon known as alignment. People align across many
dimensions including the words they choose and the affective tenor of
their prosody. ConversationAlign measures dynamics of
lexical use between conversation partners across more than 40 semantic,
lexical, phonological, and affective dimensions. Before launching into
your analyses, there are some important use caveats to consider.
Caveats for Using ConversationAlign
- Language analyses often proliferate in complexity. Spend the extra time to keep careful records and a logical organization system (e.g., smart filenaming, variable keys, a formalized processing pipeline).
-
ConversationAlignonly works on dyadic language transcripts (i.e., 2-person dialogues). -
ConversationAligndoes NOT parse turns automatically. The software will aggregate all words produced by one speaker across sentences and rows until a switch occurs in the ‘speaker’ column. -
ConversationAlignwill strip punctuation and other special characters automatically. -
ConversationAlignwill split/vectorize your text into a one-word-per-row format, retaining all variable labels. -
ConversationAlignwill retain all meta-data throughout text processing (e.g., timestamps, grouping variables).ConversationAlignis pretty good at detecting and repairing unconventional font encoding systems, but it will not catch everything, You will find all sorts of hidden junk when you copy/paste interview transcripts from random websites are from YouTube. Inspect your transcripts to make sure they are what you think they are before launching into a complex computational analysis.
Prepare your Transcripts Outside of the Package
- Save each conversation transcript as a separate file
(
*.txt,*.csv, or Otter*.ai). - Be deliberate about your filenaming convention. Each transcript’s
filename will become its unique document identifier (Event_ID) when
importing into
ConversationAlign.
- Store all the transcripts you want to analyze in the same folder (e.g., ’/my_transcripts).
- Your transcript folder and analysis scripts should ideally exist within the same directory.
- Each raw comversation transcript MUST nominally
contain at least two columns, talker/interlocutor and text.
- Name your talker/interlocutor column as ‘Interlocutor’, ‘Speaker’, or ‘Participant’ (not case sensitive).
- Name your text column as ‘Text’, ‘Utterance’, or ‘Turn’ (not case sensitive).

Here’s one from a 2013 NPR interview (USA) between Marc Maron and
Terry Gross, titled Marc Maron: A Life
Fueled By ‘Panic And Dread’.
| speaker | text |
|---|---|
| MARON | I’m a little nervous but I’ve prepared I’ve written things on a piece of paper |
| MARON | I don’t know how you prepare I could ask you that - maybe I will But this is how I prepare - I panic |
| MARON | For a while |
| GROSS | Yeah |
| MARON | And then I scramble and then I type some things up and then I handwrite things that are hard to read So I can you know challenge myself on that level during the interview |
| GROSS | Being self-defeating is always a good part of preparation |
| MARON | What is? |
| GROSS | Being self-defeating |
| MARON | Yes |
| GROSS | Self-sabotage |
| MARON | Yes |
| GROSS | Key |
| MARON | Right so you do that? |
| GROSS | I sometimes do that |
| MARON | How often? |
| GROSS | I try not to do that I do that more in life than I do in radio |
| MARON | Really? |
| GROSS | Yeah |
| MARON | Like today? |
| GROSS | Life is harder than radio |

Any analysis of language comes with assumptions and potential bias.
For example, there are some instances where a researcher might care
about morphemes and grammatical elements such as ‘the’, ‘a’, ‘and’,
etc.. The default for ConversationAlign is to omit these as stopwords
and to average across all open class words (e.g., nouns, verbs) in each
turn by interlocutor. There are some specific cases where this can all
go wrong. Here are some things to consider:
Stopwords :
ConversationAlignomits stopwords by default applying a customized stopword list,Temple_Stopwords25. CLICK HERE to inspect the list. This stopword list includes greetings, idioms, filler words, numerals, and pronouns.Lemmatization : The package will lemmatize your language transcripts by default. Lemmatization transforms inflected forms (e.g., standing, stands) into their root or dictionary entry (e.g., stand). This helps for yoking offline values (e.g., happiness, concreteness) to each word and also entails what NLP folks refer to as ‘term aggregation’. However, sometimes you might NOT want to lemmatize. You can easily change this option by using the argument, “lemmatize=FALSE,” to the clean_dyads function below.
Sample Size Issue 1: Exchange Count: The program derives correlations and AUC for each dyad as metrics of alignment. For very brief conversations (<30 turns), the likelihood of unstable or unreliable estimates is high.
Sample Size Issue 2 : matching to lookup database: ConversationAlign works by yoking values from a lookup database to each word in your language transcript. Some variables have lots of values characterizing many English words. Other variables (e.g., age of acquisition) only cover about 30k words. When a word in your transcript does not have a ‘match’ in the lookup datase, ConversationAlign will return an NA which will not go into the average of the words for that interlocutor and turn. This can be dangerous when there are many missing values. Beware!
Compositionality : ConversationAlign is a caveman in its complexity. It matches a value to each word as if that word is an island. Phenomena like polysemy (e.g., bank) and the modulation of one word by an intensifier (e.g., very terrible) are not handled. This is a problem for many of the affective measures but not for lexical variables like word length.
