Speech

Speech is a Fallout, Fallout 2, and Fallout 3 skill. In Van Buren, it was divided into two skills - Persuasion and Deception.

The ability to communicate in a practical and efficient manner. The skill of convincing others that your position is correct. The ability to lie and not get caught.

Fallout and Fallout 2
Initial Level: Starting Speech skill is equal to 25% + (2% x Charisma). Average characters will have a 35% skill.

Speech skill was in the first draft of Fallout Tactics skills, but was eventually left out.

Fallout 3
Occasionally, you will be presented with a Speech Challenge. A Speech Challenge is a response preceded by the word “Speech” and the percentage chance of success (e.g., [Speech 25%]); the higher your Speech skill, the greater the chance of success.

Succeed in a Speech Challenge, and you’ll achieve the results indicated by the response. Fail a Speech Challenge, and future Speech Challenges with that character will be more difficult.

Having a weapon draw will influence your percentage to succeed at a speech challenge.

From time to time you may also be presented with dialogue options where a word appears with no percentage (e.g., Strength or Lady Killer/Black Widow). In this case, this is a dialogue option that is available to you because of the level of the indicated S.P.E.C.I.A.L. statistic, Skill, or Perk and you will always be successful when selecting it. You only get one chance at each Speech Challenge, so if encounter one has a low percentage to succeed, you may want to exit dialogue and try the Speech challenge at a later time, after you’ve raised your Speech skill.

In order to gain a 100 in the speech skill, without directly putting skill points into it, it is necessary to only have a -2 to start with. 102 points can be obtained in game from items, perks, and quests.


 * +10 to your speech skill can be earned as a possible reward from the quest Oasis.
 * +10 for the Speech Bobblehead.
 * +50* collecting all 25 Lying, Congressional Style books.
 * +15 for the Speech perk. (+5 for each level of 3 total.)
 * +2 for the Paradise Lost book from Tulip in the Underworld.
 * +15 for the Tag! perk
 * (+2 per book with the Comprehension perk. Normally +1 without the perk.)

Strategy
In addition to counting towards the Silver-Tongued Devil achievement, successful Speech Challenges in Fallout 3 can yield the player any number of benefits: they may be rewarded with a significant increase in caps for completing quests, keys or passwords, karma, experience points, or even the chance to peacefully resolve some quests without the need for violence. However, a strong argument can still be made that -- due to how Speech Challenges are presented and implemented in the game -- the Speech skill itself is the least important in the game.

Unlike Barter (which will affect a great many transactions in the game), Speech skill will only affect specific dialogue options for the NPC's that present Speech Challenges in the game. Putting a large number of skill points into Speech -- or, even worse, selecting it as a Tag Skill -- assures that your character will be very, very adept with a fairly uncommonly occurring game mechanic.

Furthermore, whereas combat skills might increase your accuracy with a specific weapon, odds are very good that if you miss, you'll get another shot. Literally. With Speech Challenges, you only have one chance. Since even a high Speech skill will not guarantee success, if you're serious about succeeding in a Speech Challenge, you're probably going to be careful enough to save the game before rolling the dice anyway. Using this strategy, a higher Speech skill will only increase your probability of success, which translates to theoretically fewer game reloads until you succeed. Considering this, spending ten points to increase from a Speech of 30 to a Speech of 40 is likely to be completely unnoticeable in actual practice.

Since Speech Challenges always occur with specific NPC's, it is not difficult to save the game before speaking with an NPC when you know that they will offer you a Speech Challenge. (This works very well for most NPC's in the game.) In circumstances where an NPC will appear and initiate a converstation with you that will later include a Speech Challenge (such as Bryan Wilks or Lug-Nut), these events are triggered due to certain events (getting close to Grayditch or retrieving the Naughty Nightwear), so saving as soon as these criteria are met will allow you to follow the same strategy.

For some NPC's who can present multiple Speech Challenges -- such as Bryan Wilks or Vance -- it has so far been possible to choose the option to stop speaking to them after succeeding in the first Speech Challenge, save the game, and then talk to them again to attempt the second Speech Challenge.

Some food for thought: The Naughty Nightwear will grant you a +10 to Speech when worn, which will give you a slight advantage and may save you some attempts. Using the "Reload Until You Succeed" strategy and my Naughty Nightwear-boosted Speech skill in the low-30's, I have succeeded in every Speech Challenge I have encountered -- 23 so far at level 8 -- and the greatest number of reloads until success is still probably less than eight. By mid-game or later -- once Lying, Congressional Style books show up more often, and you've obtained the Bobblehead: Speech -- that number should hopefully drop to three or less, without any valuable skill points or Perks wasted on such a seldom-used skill.
