Summarizing Spanish Audio and Written Sources in One Coherent Briefing

In this lesson, you will integrate one spoken source and one written source into a single briefing organized by shared issues. You will mark agreement, addition, and conflict, attribute claims to their source, preserve numbers and limitations, and leave unresolved differences unresolved.

Source A: audio interview

Transport manager:

— During April, the number of passengers on line 8 increased by approximately 14%. Most of the growth was concentrated between seven and nine in the morning. We have also received more complaints about lack of space during that period.

— Are you going to add more vehicles?

Transport manager:

— We are studying that possibility, but there is still no final decision. First we want to review the May data.

Source B: written neighborhood report

— The neighborhood association report states that 126 residents responded to a survey about line 8. 58% said they had traveled standing at least once during the previous week. The association recommends increasing frequency between seven and nine, although it acknowledges that the survey is voluntary and does not necessarily represent all users.

Shared issue 1: greater pressure in the morning

Audio source:

— Most of the growth was concentrated between seven and nine.

Written source:

— 58% of respondents said they had traveled standing at least once during the previous week.

The sources use different evidence but point toward pressure during the same time period.

Shared issue 2: possible service change

The association recommends:

— increase frequency between seven and nine.

The transport manager says:

— We are studying that possibility, but there is still no final decision.

One source recommends action; the other confirms only that an option is under study.

Do not convert recommendation into decision

Incorrect combined summary:

— The company has decided to increase frequency.

Accurate:

— The neighborhood association recommends increasing frequency, while the company states that it is still studying that possibility.

Preserve numbers and qualifiers

Audio:

— approximately 14%.

Do not rewrite this as an exact 14.0% if the source gives an approximation.

Written source:

— 126 residents.

58 % — 58%.

Keep each number attached to what it actually measures.

Preserve the survey limitation

— The survey is voluntary and does not necessarily represent all users.

This limit should survive the integrated summary.

Organize by issue, not by source

Weak briefing structure:

— First I summarize the whole interview. Then I summarize the whole report.

Integrated structure:

morning demand and crowding
possible response
evidence limits and unresolved decision

Identify agreement

— Both sources indicate that pressure on line 8 is especially significant between seven and nine.

Identify addition

— The interview adds that total passenger numbers increased by approximately 14% in April.

— The report adds a survey about traveling standing up.

Identify unresolved difference

The sources do not actually disagree about whether frequency should increase. One recommends it; the other has not made a final decision.

Accurate:

— There is no resolved factual conflict: the association is requesting a measure that the company is still evaluating.

Model coherent briefing

— Both sources describe growing pressure on line 8 between seven and nine in the morning. In an interview, the transport manager states that passenger numbers increased by approximately 14% in April and that most of the growth was concentrated during that period. A neighborhood association report adds that, among 126 surveyed residents, 58% said they had traveled standing at least once during the previous week. The association recommends increasing frequency during the peak period. The company confirms that it is studying that possibility, but it has not yet made a decision and wants to review the May data first. The neighborhood survey is voluntary and does not necessarily represent all users, so its results should be interpreted within that limitation.

A practical multi-source briefing method

Identify the shared issues across sources.
Organize the briefing by those issues rather than writing adjacent mini-summaries.
Mark agreement, addition, and genuine conflict separately.
Attribute every claim or recommendation to the correct source.
Preserve all important numbers and qualifiers.
Keep source limitations in the integrated summary.
Do not resolve a disagreement or pending decision that the sources leave open.

From Multi-Source Briefing to the B2 Project

You can now integrate spoken and written evidence into one coherent briefing. The next lesson is the B2 project: research a public issue, write a report, and defend a recommendation.
