關於the list of Fallout 3 speech challenges,參見Fallout 3 speech challenge

口才辐射辐射2以及辐射3中的技能。In Van Buren, it was divided into two skills - Persuasion and Deception.



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.

在与NPC对话时,你经常会遇到口才挑战。当口才挑战出现时,对话的选项会以“Speech”这个单词以及成功的几率开头(如[Speech 25%]);你的口才技能越高,成功几率也就越大。



魅力口才技能都会影响你的成功几率。For example, when trying to calm Bryan Wilks down, a Charisma 6 character with 53 Speech might wear a Vault jumpsuit (+2 Speech) Dirty Business Wear (+5 Speech) or Sexy Sleepwear (+1 Charisma, which increases Speech to 55 indirectly). Charisma 6 and Speech 55 gives a 76% chance of success, Charisma 6 and Speech 58 gives an 80% chance of success, and Charisma 7 and Speech 55 gives an 82% chance of success. While it is possible to gain 100 Speech with Charisma 1, if you want the Silver Tongued Devil achievement, a high Charisma is as important as a high Speech skill.

有些时候,你将会发现一些特殊的对话选项出现,并且不附带成功率百分数(如StrengthLady Killer/Black Widow)。在这种情况下,这一对话选项之所以可用,是因为玩家角色符合其所指出的S.P.E.C.I.A.L.之一的属性、技能或特技的条件,选择这一选项将100%地成功。任何口才挑战都只有一次机会,所以如果你成功的几率较低,你可能会希望退出对话,等待口才技能提高后再来尝试。


魅力 调整值
1 100%
2 106%
3 114%
4 123%
5 133%
6 145%
7 158%
8 173%
9 189%
10 206%

据推测,准确的成功几率公式应该是魅力调整值 * 口才技能/难度。其中“难度”是依每个不同的口才检定而定,但与游戏难度等级无关。因此,将你的口才技能提高到原来的二倍,就可以获得翻倍的成功几率;与此同时,魅力则提供一种非线性的成功率增长曲线,如右表所示:

Sample difficulties for early speech checks are 215 to convince Lucas Simms to increase your reward, 147 to convince Gob to give you information, and 111 to convince Jericho to talk to you. Thus a 5 Charisma, 50 Speech character has a 66 base ability, and has a 31%, 45%, and 60% chance with these checks respectively. Having a weapon raised increases the difficulty by about 10%, so with a weapon up the chances would be 28%, 41%, and 55%.

Sheriff Simms is actually a fairly hard sell; few speech checks are harder than about 170. The hardest speech check in the game involves the AntAgonist, and is about 420.


In order to gain a 100 in the speech skill, without directly putting skill points into it, it is necessary to only have a -32 to start with. 132 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. You must pass the speech check with Sapling Yew regarding what Harold is afraid of.
  • +10 for the Speech Bobblehead.
  • +48* collecting all 24 Lying, Congressional Style books .
  • +15 for the Scoundrel 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 from Charisma bobblehead
  • +30 from the Impartial Mediation perk with Neutral Karma.
    *(+2 per book with the Comprehension perk. Normally +1 without the perk. Two books are mutually exclusive, meaning only 23/24 books can be attained, and the 23rd requires the contract killer perk, so good characters may only be able to get 22/24)

A best strategy to max out Speech while keeping to most points for other skills would be to get all the points possible from the books for approximately +48. Then get the 2 Bobbleheads for +12. This will give you +60. Your character most likely started with between 15 and 25. This gives a total of 75-85. If you want a 100, fill the rest in using normal points at a level up.

As an alternative to using precious perks to maximize this mostly useless skill (see saving strategy below), one can wear the Naughty Nightwear and Button's Wig clothing items for a +20 bonus. All together, without a single perk (Other than comprehension, which all characters should get), one can acquire +90, and with the minimum of 4 to begin, one can have 94 skill with no perks/skill/S.P.E.C.I.A.L. points invested.


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.

It is not difficult to save the game right before initiating dialogue with most NPC's in the game. In circumstances where an NPC will initiate conversations with you that can include Speech Challenges (such as Bryan Wilks, Lug-Nut, or Goalie Ledoux), these NPC's will only appear under predictable circumstances (nearing Grayditch, obtaining the Naughty Nightwear, or arriving at the Red Racer Factory); thus, saving the game just before encountering these NPC's will allow you to use the same strategy listed above.

For NPC's who can present multiple Speech Challenges -- such as Bryan Wilks or Vance -- it is 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.


What other people think of you will make a difference in your speech challenges.

For instance, speak with Dukov with a weapon drawn and you will be less likely to pass his speech check.


There is a glitch where you can talk to Pappy in Big Town and keep performing the speech challenge over and over again; this will help you gain the achievement Silver-Tongued Devil and also net you unlimited experience. Note: You have to speak to Bittercup first.

  • Note:This glitch is patched in the latest version of the game.
  • Note:"On the Xbox 360 version of fallout 3 you can get rid of the patch by going to system settings, memory, pressing the Y button when choosing storage device then selecting clear system cash then when it tells you this will perform maintenance choose "Yes" and it will get rid of all patches on your Xbox. Be careful though as this may get rid of the DLC quests on your file."

A similar (as yet unpatched) glitch occurs in Little Lamplight. When speaking to Knock Knock it is possible to repeatedly tell her that her joke is funny for esentially unlimited XP. (Ask about morale to start the tree that leads to the joke)

  • Note: If you have downloaded any DLC, and you delete the patches, you will not be able to load a saved game until you have redownloaded all required DLC's.
