Koe de Oshigoto! The Animation

Both female lead characters must learn how to become better voice actresses. 

Both are about voice actors; REC is a 15-minute per episode vignette about chance and attraction between a buisnessman and a seiyu, and Koe de Oshigoto is an OVA series about a sixteen year old girl learning to voice over eroges. Both have a nice, uncharacteristically (for the medium) low-key love element as well. 

Both are short series about a female protagonist making a name in the voice acting industry. Both series contain adult themes. Both series has comedy and some drama.  

Both are FANTASTIC Voice acting anime !!! In addition, the girl in both anime voices an eroge part. Rec is more romance while Koe is more ecchi, BOTH ARE AWESOME RECOMMEND ^^ 

The story revolves around a girl striving and pursuing her dream to become a seiyuu. 

Both are anime about voice acting. Koe de Oshigoto is about the production of hentai games, use headphones. 

Two comedies taking place in the porn production industry. In both the framing device is a newcomer to the industry who learns on the job. Both have a similar humor, which plays with the sober and professional approach to ... producing smut for money. Both anime take the time to at least superficially introduce an ensemble cast to showcase the different professions. Animation wise they are over 20 years apart, with Bouken Shite being low budget even at it's time. Yet, they share roughly the same degree of ecchiness and humor. 

Both shows involve students working in the eroge industry (Porn LN writer in R-15 and VA in Koe). Both shows also feature protagonists who let their imaginations run wild in certain situations 

*It's not a kawaii school anime. Conversations are extremely perverted. So, don't suggest watching this to your younger brother or sister (or to parents) ^_^ *The main character is a schoolgirl with innocent look. *...However, she always says dirty things. In KdO she have to say them (because it's her work) and in SY she just like to they them. *In KdO she hides the fact that she has such kind of job. And in YK she doesn't. However, in both cases not so many people are acknowledged about her second nature. *She have two female friends in school. So, there is a trio of girls in both anime, they look pretty similar in some way. One of the girls is a twin tales pettanko with low height. However, in KdO she is not tsunderish enough to fit this trope. *There is a romantic line on the background. In SY it's lost in perverted jokes, and in KdO it fits a plot good. read more 

The main heroines of these series very often find themselves in hilarious situations with sexual context, which would leave the viewers laughing long after the scene ends. Yamada from "B Gata H Kei" dreams only about how to loose her virginity and, as a result, most of hilarious situations comes from her failed attempts to do so. Aoyagi Kanna from "Koe de Oshigoto!" on the other hand does not have perverted thoughts at all but tries to be an eroge seiyū. Hilarious situations comes from her failed attempts as well as successful ones. But it would be unfair to say that both are only about sex and sexual jokes. There is also romance involved, which for "Koe de Oshigoto!" is better presented in manga version. read more
